Weekly GCSE Science Exam Practice – P1 Mock Mix Up

A recorded GCSE Science Exam Practice session designed to build confidence for Paper 1 mocks.

This week is a Paper 1 Mock Mix-Up, with Biology, Chemistry and Physics questions covering key topics that students are likely to encounter in their mock exams.

Students begin with a clean set of exam-style questions to attempt independently. They then work through the recording with me, learning how to interpret each question, identify the science being tested and build answers that gain marks.

This week’s session covers:

• Digestive enzymes and the breakdown of food molecules

• Investigating the effect of pH on enzyme activity

• Plotting graphs, identifying optimum conditions and explaining enzyme denaturation

• The role of bile in fat digestion

• Preparing soluble salts and growing crystals

• Writing balanced symbol equations

• Required practical techniques and laboratory safety

• Calculating moles, relative formula mass and masses of products

• Comparing alpha, beta and gamma radiation

• Choosing suitable radioactive isotopes for medical tracers

• Calculating radioactive half-life and count rates

Included:

• A printable 38-mark Paper 1 Mock Mix-Up workbook

• A recorded, step-by-step walkthrough of every question

• Fully annotated answers to download after completing the session

Suitable for AQA Combined and Separate Science students in Years 10 and 11. The content is based on Higher Tier expectations, although much of it is also relevant to Foundation Tier students.

Please note: this is a recorded session, not a live lesson.

This session is available immediately after purchase, but access ends at 11:59 pm on Sunday 8 November 2026, regardless of the purchase date.

A fresh GCSE Science Exam Practice session will become available on Monday 9 November 2026.
