IGCSE Biology and Chemistry teacher with more than 20 years of classroom and exam-preparation experience.
Select the subject your child is preparing for. Each page explains what is included and gives access to the correct solved past paper course.
For students who need clearer Biology answers, examiner-style wording, and help with long-answer questions, practical questions, keywords, and command words.
For students who struggle with short mark-scheme answers, calculations without working, chemical explanations, practical chemistry, and writing answers that score marks.
IGCSE mark schemes are useful, but they are not designed to teach students how to write answers. They are mainly written so teachers and examiners can mark student responses consistently. That is why many mark-scheme answers are short, blunt, and difficult for students to understand.
A student may see one or two key words in a mark scheme and think that is enough. In the real exam, however, the answer often needs a clear idea, accurate scientific language, and the correct link between cause and effect. This is especially important in IGCSE Biology and IGCSE Chemistry, where students often know the content but still lose marks because they do not phrase the answer in the expected way.
In many questions, the mark scheme gives the final answer without showing how a student should reach it. This is a major problem in Chemistry calculations, graph questions, practical questions, and structured Biology explanations. Students need to see the steps, not just the final word or number.
Without a proper explanation, students may keep repeating past papers without improving. They check the answer, move on, and then make the same mistake again in the next paper because they never understood what the examiner was really looking for.
After watching students struggle with exam questions for many years, I created these IGCSE solved past paper courses to remove the gap between the mark scheme and the student. The aim is not just to give an answer. The aim is to show students how to write answers that actually score marks.
Each solved paper includes expert-written answers and video walkthroughs. In the videos, students can solve along with me, pause, repeat, and understand why the answer is written in that exact way. This gives students a stronger reference than a normal mark scheme and helps them prepare more confidently for the 2026 and 2027 exams.
By the time students reach the final weeks before the exam, they should not be guessing how to answer. They should have a clear model of what a high-quality answer looks like. That is the purpose of this hub: to guide students to the Biology or Chemistry solved past paper course that gives them that model.
Feedback from students who used written answers together with video walkthroughs to understand the mark scheme properly.
I used to waste so much time scrolling through mark schemes and still not understand the answer. The videos helped me solve along with the teacher and finally see why each mark was given.
The written answers were much clearer than the normal mark scheme. I liked that the videos showed the exact way to build the answer, especially for long Biology questions.
The best part was solving while watching the video. Instead of just checking if I was right or wrong, I understood the working and saved a lot of revision time.
The mark scheme always felt too short for me. These answers explained what I should actually write, and the videos made the exam technique much easier to follow.
For Chemistry calculations, I needed the working out, not just the final number. The solved answers and videos helped me understand the method and avoid repeating mistakes.
I saved so much time because everything was explained in one place. I could watch the question being solved and then copy the answer style into my own practice.
Start with the correct subject page, then use the solved answers and videos as a proper reference for exam practice.
