✍️ Sample A-LEVEL Questions & Answers
1. What is the key feature that distinguishes an experiment from a correlational study?
The defining feature of an experiment is the deliberate manipulation of an independent variable (IV) while measuring its effect on a dependent variable (DV), with control of extraneous variables. Correlational studies only measure the relationship between co-variables without manipulation.
2. What is the role of oestrogen in controlling the menstrual cycle?
Oestrogen has complex feedback effects: at low levels it negatively feeds back to inhibit FSH/LH. At high levels near ovulation, it provides positive feedback triggering the LH surge. It also repairs and thickens the endometrium after menstruation.
3. What is dramatic irony?
Dramatic irony occurs when the audience possesses knowledge that characters lack, creating tension or humour. In 'Romeo and Juliet', the audience knows Juliet is not truly dead, making Romeo's suicide deeply tragic.
4. What is a buffer solution and how does it resist pH change?
A buffer contains a weak acid (HA) and its conjugate base (A⁻, from a salt). Adding acid: A⁻ + H⁺ → HA (base removes excess H⁺). Adding alkali: HA + OH⁻ → A⁻ + H₂O (acid neutralises OH⁻). pH change is minimal.
5. What is the difference between elastic and inelastic collisions?
In elastic collisions, kinetic energy and momentum are both conserved (e.g., billiard balls). In inelastic collisions, momentum is conserved but kinetic energy is not — some is converted to heat, sound, or deformation.
6. El Niño is associated with which of the following ocean and atmospheric conditions?
El Niño is characterised by unusually warm sea surface temperatures in the central and eastern Pacific Ocean, which disrupts normal atmospheric circulation and weather patterns globally.

What Practice Test Geeks adds beyond an AI chat for A-Level
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length A-Level mock exam — 60 questions in 90 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed A-Level question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable A-Level cheat sheet you can print or save as a PDF.
- A-Level flashcards built from the same question bank.
- Free A-Level practice tests with the correct answer shown after each question.
