Question 1

How do I know if I've properly learned a topic in Physics?

Accepted Answer

The clearest sign that you've genuinely learned a topic is when you can recall and apply the ideas without looking at your notes. For Cambridge IGCSE Physics (0625), that means two things: you can remember the facts, definitions and equations (AO1, Knowledge with understanding), and you can use them to solve unfamiliar problems in contexts you haven't seen before (AO2, Handling information and problem solving).

Our quizzes are a good place to test both, since they surface questions you'd struggle to bluff your way through by half-remembering. We'd also suggest the blurt technique after a study session: close your notes, write down everything you can recall from a topic, then check what you missed. If you can work through our exam-practice questions without going back to check a formula or definition, that's a strong signal the content has stuck.

Question 2

How often should I quiz myself when revising IGCSE Physics?

Accepted Answer

Spacing your quizzes out across the week tends to strengthen recall far more than cramming everything into one long sitting, and the research on spaced retrieval consistently backs this up. A good rhythm would be quizzing yourself on a topic shortly after you first study it, then returning to the same material a few days later, and again a week or so after that.

For Cambridge IGCSE Physics (0625), which covers six topic areas, you could rotate through them so each one gets revisited regularly rather than left untouched for weeks. Our quizzes are built by topic, so you can target whichever area feels shakiest and return to it in your next session. We'd suggest aiming for several shorter quiz sessions spread through the week rather than one big block at the weekend.

Question 3

Should I do a quiz before or after reading the notes?

Accepted Answer

Both approaches have genuine value, and the best choice often depends on where you are in your revision cycle. If you're encountering a topic for the first time, we'd suggest trying the quiz first.

This is called pre-testing, and it primes your brain to notice and absorb the information when you read the notes straight after. If you've already been through the notes once, doing the quiz afterwards is a great way to check what has stuck and flag any gaps to revisit. Our quizzes are built around the Cambridge IGCSE Physics (0625) Extended content, so either way you're working through the right material.

Question 4

What's the difference between Cognito's quizzes and the actual exam questions?

Accepted Answer

Our quizzes are built for retrieval practice, helping the content stick through repeated testing of what you know. The actual Cambridge IGCSE Physics exam tests two main things across the written papers: knowledge and understanding (AO1, worth 50%) and handling information and problem-solving (AO2, worth 30%), so exam questions often ask you to apply ideas to unfamiliar situations rather than simply recall them.

Paper 2 is 40 four-option multiple-choice questions, while Paper 4 uses short-answer and structured written questions that reward the ability to explain and calculate. We'd suggest using our quizzes to build solid content knowledge first, then moving to our exam practice to get familiar with the question styles CIE use in the real papers.
