Sample question

Physics · P1.2.2 Conservation and dissipation of energy

State — 4 marks

A student is investigating the motion of a toy car rolling down a ramp. The car starts from rest at the top of the ramp and accelerates uniformly as it travels downwards. The student measures the distance travelled and the time taken to reach the bottom.

  • (a) State what is meant by uniform acceleration. [1 mark]
  • (b) The toy car travels 2.0 m in the first second. State the distance it travels in the second second if it is accelerating uniformly from rest. [2 marks]
  • (c) State the name of the physical quantity that measures how quickly the velocity of the car is changing. [1 mark]

  • (a) Uniform acceleration is when velocity changes by the same amount in equal time intervals
  • (a) OR: Constant acceleration / acceleration that does not change
  • (b) 6.0 m (1 mark for correct numerical answer)
  • (b) Using s = ut + ½at²: if s₁ = 2.0 m in first second, then a = 4 m/s², so s₂ = 0 + ½(4)(2²) - ½(4)(1²) = 8 - 2 = 6.0 m (1 mark for correct working or reasoning)
  • (c) Acceleration

Spaced repetition

The app tracks what you know and schedules the right questions at the right time — so you remember more with less effort.

📊

Exam frequency signals

Each topic is tagged with how often it appears in past papers. Focus your revision on High-frequency topics first.

How it works

1

Sign up free

No card, no ads. Your data stays local. Create an account and pick a subject.

2

Practise a session

The app picks questions from your weakest topics using the SM-2 spaced repetition algorithm.

3

Track your grade

Self-mark against the scheme. The dashboard shows your predicted grade, streak, and weak spots.

Frequently asked

Is it really free?

Yes. No hidden costs, no ads, no "freemium" gates. If that changes in the future, existing accounts will keep their current features.

Which exam board?

GCSE Perfect is aligned with the UK Department for Education GCSE subject content — the national curriculum every UK GCSE exam board is required to cover. That means it works for students preparing for any UK GCSE exam board, not just one.

Where do the questions come from?

They're original, written by a large language model to match the UK Department for Education GCSE subject content, then automatically reviewed against a student-harm policy (no factual errors, no misleading mark schemes) before being published. Every question is checked.

What is spaced repetition?

A study method that schedules each question for review right before you'd forget it. The app uses the SM-2 algorithm — the same one used by Anki — so you remember more with less total study time.

Does it work offline?

Not yet — you need a connection to load sessions. The underlying data is local to the server, not sent to any third party for tracking.
