A disappointing Chemistry mock: what parents can do next

A low mock mark can be upsetting. It is useful evidence about what your child could do on that paper, on that day. It is not their final GCSE or A-level grade. The practical next step is to look at the marked work with your child and their teacher, then choose a small number of things to improve.

Put the result in context

Schools and colleges run and mark mocks. They may use exam board questions and mark schemes, but an indicative mock grade is not an awarded qualification grade. Ask which topics had been taught, which papers were used, what grade boundaries were applied, and whether there were circumstances such as illness or an agreed access arrangement that affected the attempt. Ofqual explains that final exam boundaries are set after marking and may vary by year.

Ofqual also asks centres to retain suitable assessment evidence, often from mocks, in case national exams cannot go ahead. That resilience guidance is a contingency arrangement, not a promise that a mock will become a final grade. It asks schools to avoid unnecessary extra testing, and says teachers should make clear to students that an indicative grade is not an indication of what their final grade would be if a grade had to be awarded using that evidence.

Read the marked paper, not only the grade

Ask your child which questions they understood, which they guessed and which they could not finish. If the school can share a copy of the marked script, look for patterns:

• Chemistry knowledge: Was a definition, reaction or explanation missing or mistaken?
• Applying knowledge: Could your child use a familiar idea in a new context, such as interpreting a practical result?
• Question wording and exam response: Did they miss an instruction such as explain or evaluate, or give too little evidence for the marks available?
• Calculations: Were the formula, rearrangement, units, working or final answer the problem?
• Time and conditions: Were later questions blank, or did nerves or an access issue affect the work?

These are prompts for discussion, not a formal way to classify every lost mark. A single answer can show more than one issue. AQA GCSE Chemistry tests knowledge, application and analysis across the qualification; its published assessment-objective percentages do not tell you the exact mix in one school mock. Practical knowledge and skills can also appear in written questions.

Match practice to the difficulty

For a knowledge gap, use short self-quizzes and return to the topic on later days. For application, attempt new questions and explain why a Chemistry idea fits the evidence. For question wording, compare an answer with the exam board's mark scheme and rewrite it accurately. For calculations, practise a few worked examples with units before trying mixed questions. For timing, practise a manageable section under timed conditions and review what was skipped.

Do not simply repeat the same marked questions until the answers are memorised. Try a different question on the same idea after a week or two to see whether the improvement transfers. The Education Endowment Foundation's guidance supports teaching students to plan, monitor and evaluate their learning; parents can help by asking, “What will you practise this week, and how will you know it helped?”

Speak to the teacher

Take two or three specific questions to the teacher:

• Which topics or types of response cost the most marks?
• What had not yet been taught when the mock was set?
• What is the highest-priority practice before the next assessment?
• For a GCSE student, does this result affect the planned Foundation or Higher entry?

Agree a realistic routine with your child. Review another set of questions after a few weeks and adjust the plan. If the result caused significant distress, start by listening and speak with the school about support.

Where to go next

Use your child’s marked mock paper to identify specific difficulties and agree focused practice with their teacher.
