How to Prepare for Cambridge IGCSE Biology February/March 2027 in India: Dates, Grade Targets and a 16-Week Plan

What is the Cambridge IGCSE February/March series, and who sits it?

The February/March series is Cambridge's exam sitting for schools in India, timed so that results arrive in May alongside the national boards. Cambridge states that it introduced the March exam series in India in 2015 following demand from schools, and that the timing lets students receive results in time for First Year Junior College admissions.

If you are reading this from Mumbai, Chennai, Hyderabad or Bengaluru, this is almost certainly your series. The syllabus you are examined on is the same one used worldwide. The front page of the Cambridge IGCSE Biology 0610 syllabus for 2026, 2027 and 2028 says the exams are available in the June and November series and "also available in the March series in India". Nothing about the content, the papers or the grading is different for you.

What is different is the calendar. You sit in February, you get results in May, and the question papers from your series stay locked until after results day. That last point matters for your past-paper strategy, and I come back to it below.

When are the IGCSE Biology February/March 2027 papers?

The March 2027 series starts on 3 February 2027 and ends on 4 March 2027, with results released on Direct on 13 May 2027. Those dates come from the official Cambridge key dates for the March 2027 exam series, and the same document lists the final entries deadline as 27 November 2026 and the late-entries deadline as 14 December 2026.

Your three Biology papers sit on three separate mornings inside that window. The Cambridge final timetable for the March 2027 series lists Paper 5 and Paper 6 on Tuesday 16 February 2027, Paper 3 and Paper 4 on Thursday 18 February 2027, and Paper 1 and Paper 2 on Thursday 4 March 2027, all in the AM session. Your school's exams officer has the same timetable with your start times, so confirm them now and write the three dates on the front of your notes. Note the order: the practical skills paper comes first, the theory paper two days later, and the multiple choice two weeks after that. The Cambridge monthly calendar for the March 2027 series also gives you the later milestones: results despatch in early June and certificates in late June 2027.

One practical note for parents. The entries deadline of 27 November is your school's deadline, not yours, but it is worth confirming with the school before then that your child is entered for the Extended papers if an A or A* is the target. The grade range depends on that entry, as the next section explains.

Which papers will you sit, and what is each one worth?

Every IGCSE Biology candidate sits three papers: a 45-minute multiple-choice paper worth 30%, a 1 hour 15 minute theory paper worth 50%, and a practical component worth 20%. The 0610 syllabus assessment overview sets this out: Core candidates take Papers 1 and 3 and are eligible for grades C to G, while Extended candidates take Papers 2 and 4 and are eligible for grades A* to G.

For the practical component, your school enters you for either Paper 5 (a practical test, 1 hour 15 minutes) or Paper 6 (Alternative to Practical, 1 hour). Both are worth 40 marks and 20% of the grade, and both are based on the experimental skills in Section 4 of the syllabus. Most schools in India enter students for Paper 6, and I write this post assuming you are one of them.

The syllabus also weights what it is testing. Knowledge with understanding (AO1) is 50% of the marks, handling information and problem-solving (AO2) is 30%, and experimental skills (AO3) is 20%. Half the marks are for knowing the biology. The other half are for doing something with it under exam conditions, which is where most of the preparation time should go.

Here is the structure for the Extended route, alongside the grade A threshold each paper carried in March 2026.

Paper	What it tests	Time	Raw marks	Weighting	Grade A minimum, March 2026
Paper 2	Multiple choice (Extended), 40 four-option questions	45 min	40	30%	32 / 40
Paper 4	Theory (Extended), short-answer and structured	1 h 15 min	80	50%	57 / 80
Paper 6	Alternative to Practical, experimental skills	1 h	40	20%	31 / 40
Syllabus	Weighted total	—	200	100%	A* 171 · A 150 · B 129 · C 109

Paper structure from the Cambridge 0610 syllabus for 2026–2028; thresholds from the Cambridge grade threshold table for 0610, March 2026. If you want the topic list behind these papers, my 2026–2028 IGCSE Biology syllabus guide walks through all 21 topics.

What marks did an A* need in March 2026?

In the March 2026 series an A* on the Extended route needed 171 of 200 weighted marks, an A needed 150, a B needed 129 and a C needed 109. These figures are published in the Cambridge grade thresholds for IGCSE Biology 0610, March 2026, and they are the most useful numbers in this post because they turn "I want an A*" into a mark you can measure yourself against every week.

Cambridge does not award A* at component level, but it does publish the component thresholds for grade A: 32 out of 40 on Paper 22, 57 out of 80 on Paper 42 and 31 out of 40 on Paper 62. An A* at syllabus level works out at about 86% across the three papers. So when you sit a timed Paper 4 in December and score 58, you are at the grade A line on that paper, with ground still to make up for an A*.

Two things stand out from the table. First, the Paper 6 threshold for an A is 31 out of 40, which is 77.5% on a paper many students treat as an afterthought. Second, the Core route tops out at grade C, and in March 2026 that C needed 122 of 200. A student who could score 65% on Extended papers would reach a B; the same student entered for Core cannot be awarded anything above a C. That is why the entry decision in November matters.

Keep these thresholds in front of you, and keep in mind that they shift a little every series. When I score practice papers with students, I use the most recent published thresholds as the target line, and so should you. My classified IGCSE Biology solved past papers are organised by topic so you can measure yourself against that line one topic at a time, not only on full papers.

Has the 0610 syllabus changed for 2027?

No. You are examined on the same 0610 syllabus for 2026, 2027 and 2028, and the most recent revision did not change any content. The Cambridge syllabus update notice for 0610 records that version 3, published August 2026, updated only the assessment overview page, and that version 2, published December 2025, updated a web link.

This is good news for you, because it means every past paper from the 2023 series onwards was set on content that overlaps almost entirely with yours, and every set of notes written for the 2026 syllabus is still correct. If you are using older notes written for the 2023–2025 syllabus, check them against the current topic list before you rely on them, because a few statements were reworded in the 2026 revision. My IGCSE Biology and Chemistry notes eBook is written for the 2026–2028 syllabus and in the language of the mark schemes, which is what you want for the writing practice that comes next.

A 16-week preparation plan from mid-October to 3 February

From mid-October to the start of the series you have about 16 weeks, and the plan that works is to give every week two sessions: one to learn the content of a topic in exam terms, and one to solve Paper 4 and Paper 6 questions on that topic while practising Paper 2 questions on it yourself. That is how I run my own classes for February/March students every week, and it is the loop the recorded course follows.

Here is how I structure it.

Session one of the week is content. I explain the topic while focusing on the exam content and the terms students have to master, not everything that could be said about the biology. Every topic has a set of words the mark scheme expects, and a student who can define and use those words correctly has done most of the work for Paper 4.

Session two, the next day, is solving. We work through Paper 4 and Paper 6 questions on the same topic together, and students practise Paper 2 questions on that topic during the day. The practice is guided. The point of solving the day after learning is that the content is still fresh, and the questions show immediately which terms did not stick.

The recorded version of that loop is what you get in my IGCSE Biology self-study course: 60 lessons of about 75 minutes each, Paper 2 quizzes, Paper 4 and Paper 6 solved papers, and WhatsApp support when a question will not come out. The students who completed it last June did well: 74.0% of my IGCSE Biology students scored an A or A* in June 2026.

Lesson 1 of the free sample: the full lesson video, with jump links to each chapter and a second video that solves exam questions on the same topic.

Spread across 16 weeks, the plan looks like this.

Weeks 1–6 (mid-October to late November): content sweep with solving. Cover the 21 topics at a rate of three to four a week, using the two-session loop. Do not skip the solving day to "get through" more content. Half-learned topics with no question practice are what produce a C in February.

Weeks 7–10 (December): topic-classified past papers. Now switch the balance towards papers. Work through Paper 4 questions by topic, so that every question on enzymes sits next to every other question on enzymes and the pattern of what Cambridge asks becomes obvious. Mark against the mark scheme, and record every lost mark with the reason.

Weeks 11–13 (early to mid-January): Paper 6 skills and investigations. You have been building these since October, as the next section explains. January is when you sit full Paper 6 papers under time.

Weeks 14–16 (late January to 3 February): full timed papers. Sit whole papers, in order, against the clock, and score them against the thresholds above. By the final week you should know your mark on each paper to within a few marks.

Start with a free sample lesson from the course if you want to test the loop before committing to it. The free Cambridge IGCSE Biology sample lesson includes two full lesson videos, the notes, a topic quiz and trial Paper 2, Paper 4 and Paper 6 question packs with answers.

Each topic ends with a quiz ladder, flashcards and a one-page revision sheet. This is the "check" step before you move to past-paper questions.

How do you prepare for Paper 6 when it is 20% of the grade?

Paper 6 tests experimental skills, not recall, so it has to be practised slowly and early in the year rather than crammed in January. The syllabus states that both Paper 5 and Paper 6 are based on the experimental skills in Section 4, and that section is about drawing, measuring, tabulating, plotting and evaluating, none of which can be memorised the night before.

Paper 6 requires practice. This has to be done earlier in the year. It is based on skills students have to develop slowly: drawing biological drawings, drawing graphs and creating tables. All of this requires slow learning while the skills develop, and I would put it this way to any student starting in October: do one Paper 6 skill a week from now until January, and you will walk into that paper with 31 out of 40 well within reach.

In addition, you need to know the essential investigations. The ones that come up again and again are the enzyme investigations (the effect of temperature or pH on an enzyme reaction), anaerobic respiration in yeast, and photosynthesis (testing a leaf for starch, and the factors that affect the rate). Learn each one as a method: the independent variable, the dependent variable and how it is measured, the variables you control, the safety point, and the shape of the result. When Paper 6 shows you a table of results from one of these, you should already know what the graph will look like before you draw it.

The trial Paper 6 pack covers measurements, tables, graphs, food tests, variables and evaluation: the exact skill set Section 4 of the syllabus examines.

Three habits that earn Paper 6 marks every time:

• Tables before graphs. Headings with units, independent variable in the first column, and every reading to the same number of decimal places.
• Graphs that an examiner can read. Axes labelled with units, a scale that uses more than half the grid, points plotted as crosses, and a line that fits the data rather than joining every point when a curve is clearly expected.
• Biological drawings with no shading. Single clear lines, a size that fills the space, labels with ruler-drawn label lines, and a magnification calculation shown in full.

The Paper 6 solved papers in my solved past papers bundle show each of these done for the marks, with the mark scheme alongside, which is the fastest way to see what a 40-mark answer looks like.

Where March-series students lose marks

Students lose marks not because of a lack of knowledge. Most of the time it happens because they struggle to understand what the question is asking.

A student who knows the biology of osmosis will still lose the marks on a question that says "explain" if the answer only describes, or lose them on a question that says "suggest" if the answer tries to recall a definition instead of applying an idea to a new situation. The mark scheme is written to the command word, and an answer that ignores the command word is marked as if it answered a different question.

This usually comes with practice. Once a student masters the command words, they understand much more clearly what the examiners are requesting from each question, and that makes the way they write answers much more efficient. Here is the short list I drill:

• State / Give / Name: one short point, no explanation.
• Describe: what happens, in order, with the data or the observation. No reasons.
• Explain: reasons. Every "because" earns a mark; every description without a "because" earns nothing.
• Suggest: apply what you know to a situation you have not seen. The mark scheme accepts any sensible answer that uses the correct biology.
• Compare: both things, in the same sentence, with the point of difference named.

The other patterns I see repeatedly: percentage-change calculations with the wrong denominator, magnification calculations with units left in, and Paper 2 answers changed from the right option to the wrong one in the final five minutes. The cure for all of them is the same: more papers, marked properly, with the lost marks written down.

One more thing worth saying because students ask every year. In terms of difficulty, the March and the June papers are at the same level. A March paper is not easier, and it is not harder. It is the same syllabus, the same assessment objectives and the same standard.

Can you use June and November past papers to prepare for March?

Yes, and you should, because June and November papers test the same syllabus to the same standard, and the February/March papers from your own series are not released until after results day in May. Cambridge publishes the series on the same 0610 syllabus with the same assessment overview, so a Paper 4 from June 2024 is as good a rehearsal for your February paper as any March paper would be.

I would say that students have to complete as many papers as possible, but definitely try to solve all the papers from 2023 onwards. That gives you three series a year across three years, which is more than enough to see every topic examined several times in several different ways. Work through them in this order:

1. By topic first(December). Every Paper 4 question on a topic, back to back, so the patterns show.
2. By paper second(January). Whole papers, under time, scored against the thresholds.
3. Paper 2 throughout. Multiple choice is the paper students under-practise because it looks easy. It carries 30% of the grade, and the A threshold was 32 out of 40 last March. Do a set every week from October.

Papers that are solved and marked against the mark scheme teach you more than papers that are only attempted. My classified past papers hub is built for the "by topic" stage, and every answer is written in the language the mark scheme rewards.

FAQ

How do I study for IGCSE Biology? Learn each topic in exam terms, then solve Paper 4 and Paper 6 questions on it the next day while practising Paper 2 questions yourself. Repeat that two-session loop every week, and switch to topic-classified then full timed past papers from December.

Is IGCSE Biology difficult? It is a content-heavy subject with 21 topics, but the marks are lost on exam technique more than on biology. Students who master the command words and practise Paper 6 skills early find the papers predictable; in March 2026 an A needed 150 of 200 weighted marks.

What grade is 70% in IGCSE Biology? On the Extended route in March 2026, 70% of the weighted total is 140 marks, which sat inside the grade B band (B began at 129 and A at 150). Thresholds change slightly every series, so check the latest published table for your sitting.

Is D a pass or a fail in IGCSE? Cambridge awards grades from A* to G on the Extended route and C to G on Core, and a D is a certificated grade on both. Whether a D meets an entry requirement depends on the school, college or university you are applying to, not on Cambridge.
