How it works

Four moves per chapter. Always the same four.

Learners never have to work out what to do next. The chapter tells them.

1

Learn the essentials

Start with a visual summary built only from what Cambridge actually tests — no textbook filler, just what comes up in the papers.

2

Lock it in with flashcards

Tap to flip: question on front, one clean answer on back. The deck remembers where you stopped.

3

Prove it in quizzes

Sets of six questions. Get one wrong and it explains on the spot, then brings it back before the round ends. Earn three stars only if you get all six right the first time.

4

Push further with structured questions

Full exam-style questions, marked against the real Cambridge mark scheme — see exactly where every mark is won or lost.

Built from past papers

We read the papers, so you only learn what they ask.

Most study sites summarise the textbook. We do the opposite. Every summary, flashcard and question is built from real Cambridge past papers (0610 & 0620) — so nothing on Apex is there unless it actually comes up in the exam.

  • Every past paper read question by question, not skimmed.
  • If it's in the book but never tested, it's not here.
  • Less to study, and all of it counts.

What we keep, what we cut

  • Osmosis in plant tissueasked again and again
  • Active transport of mineral ionsasked again and again
  • Enzyme active site & denaturationasked again and again
  • History of the microscopenot tested
  • Plant tissue culture & cuttingsnot tested

We keep what Cambridge asks. The rest doesn't make the cut.

Quizzes

We never let a mistake pass.

Get one wrong and the answer is explained on the spot. The question then goes to the back of the queue and comes round again before the quiz ends. A round only ends when every question has been answered correctly.

  • Explanations written in plain English for ages 13–17, never copied from the textbook.
  • Miss a few and they come back before you finish.
  • The more you get right the first time, the more stars you earn.
  • Three levels, easy, medium and hard, with explanations focused on the tougher questions.
Medium

Which gas do plants take in during photosynthesis?

Nitrogen
Oxygen
Carbon dioxide

Oxygen is what the plant gives out. Carbon dioxide is what it takes in and turns into glucose.

Structured questions

Marked the way an examiner would mark it.

Biology · Chapters 5–66 marks

Explain how the structure of a leaf helps it carry out photosynthesis.

4/6

Strong answer: two marks to go

You explained the surface and the chloroplasts well. Add gas exchange and you have the lot.

  • Large surface area for light absorption
  • Palisade cells packed with chloroplasts
  • Stomata allow carbon dioxide in
  • Thin, so gases diffuse quickly

Long-answer questions marked against the real Cambridge mark scheme. Write your answer, and see exactly which points earned a mark and which were missed.

Built to sharpen your answers before exam day.

AI Tutor

It only knows what the course knows.

The tutor is locked to the Biology and Chemistry material on this platform. Every answer names the chapter it came from, and anything outside the syllabus gets a straight "I could not find that", never a made-up answer.

  • The source chapter is shown on every answer.
  • No open web, no general chat.
  • A daily limit, so it stays a study tool.
Study tutor

Why do leaves look green?

Chlorophyll soaks up red and blue light and bounces green light back at your eyes, so green is the colour the leaf does not use.

From Biology · Chapter 4

Can you help with my maths homework?

Maths is not one of my subjects. I only know the Biology and Chemistry in your chapters. Ask me about either and I will find it.

Who built this

Built by someone who's sat the exam and taught it.

Apex Study was created by Colomba Lira — marine biologist, former IGCSE student, and private IGCSE Biology and Chemistry tutor for over five years. Every chapter reflects years of seeing what students miss and what earns marks in the real exam.

  • Marine biologist

    The science behind the chapters is her own field.

  • Sat these exams

    IGCSE Biology and Chemistry, as a student first.

  • Five years tutoring

    0610 and 0620, one student at a time.

  • Every chapter hers

    Written and checked by her, not licensed in.

For parents

One family account, two students, nothing hidden.

Questions

Before you sign up

Which syllabus does it follow?

The chapters follow Cambridge IGCSE Biology (0610) and Chemistry (0620), in the order the syllabus teaches them.

What age is it for?

Thirteen to seventeen. Younger learners lean on the flashcards and visual summaries; older ones spend most of their time in quizzes and structured questions.

Can more than one child use it?

Yes, up to two sibling profiles on one subscription, each with its own progress, streak and XP, and an optional PIN.

What devices does it work on?

Any device with a browser — phone, tablet or laptop. Nothing to install, just log in and study.

Is the AI Tutor safe?

It can only draw on the Biology and Chemistry material on this platform, it names the chapter behind every answer, and it has a daily limit.
