Edexcel IAL Chemistry October 2026 practice papers from Tyrion Papers cover Units 1–6 and include full worked solutions for the units you select. The collection offers individual papers, an IAS Units 1–3 bundle, a Units 4–6 bundle and a complete subject set in digital PDF format.
If you want additional Chemistry mock questions or a fresh timed attempt after working through familiar past papers, these independently created predicted practice resources can help. This article explains the options and a practical way to review equations, calculations and chemical explanations. They are not official Pearson papers and do not guarantee future exam questions.

Qualification: Pearson Edexcel International AS & A Level Chemistry. Codes: WCH11–WCH16. Included: the selected question papers and their solutions.
Choose the correct Chemistry unit before downloading
Your exam entry determines which resources you need. Check the qualification and unit code with your centre. Edexcel International A Level Chemistry, UK A Level Chemistry and International GCSE Chemistry are different qualifications; their papers are not interchangeable.
| Unit | Code | Practice options |
|---|---|---|
| Unit 1 | WCH11 | Individual paper, IAS bundle or complete set |
| Unit 2 | WCH12 | Individual paper, IAS bundle or complete set |
| Unit 3 | WCH13 | Individual paper, IAS bundle or complete set |
| Unit 4 | WCH14 | Individual paper, Units 4–6 bundle or complete set |
| Unit 5 | WCH15 | Individual paper, Units 4–6 bundle or complete set |
| Unit 6 | WCH16 | Individual paper, Units 4–6 bundle or complete set |
Each option includes solutions for its selected units. For a single-unit resit, start with the relevant unit. If you are revising several units, compare the bundles on the product page rather than buying papers you will not use.

How to review a Chemistry practice paper effectively
Show a complete calculation route
Write the relationship you intend to use, show substitutions and carry units consistently. During review, find the first incorrect step rather than only comparing final answers. Redo the calculation without the worked example, then check whether you can apply the approach to a different question.
Check equations and chemical symbols
Review formulae, balancing and any state symbols or conditions required by the question. An equation can expose a misunderstanding that a paragraph hides. Keep a short record of repeated equation errors and revisit it before your next timed attempt.
Explain chemistry rather than repeat a phrase
For explanatory answers, name the relevant particles, interactions or process and connect them to the observation. Check that your reasoning answers the actual question. A statement that is true in general may still be incomplete for the particular context.
Organise organic chemistry errors
Where organic content is relevant to your unit, separate mistakes in structures, reaction choices, conditions and explanations. Practise drawing and explaining without notes. Use your current specification to check coverage instead of treating one practice paper as a list of everything that matters.
Include practical and data-handling reasoning
Practise interpreting results, choosing measurements and discussing limitations wherever relevant to your entered units. Written questions help rehearse analysis, but laboratory skills still need appropriate teacher-supervised preparation.
A simple attempt–review–retry routine
- Attempt: follow the paper’s printed timing and instructions, with solutions closed.
- Review: compare your reasoning with the solution and classify the error.
- Repair: revisit the precise concept, equation or calculation step.
- Retry: solve the question independently and attempt a fresh example later.
Do not let checking become copying. If you can follow a solution but cannot reproduce the method without it, that topic still needs work. Leave enough time between papers to act on their feedback.
Are predicted papers a substitute for official past papers?
No. Official Chemistry past papers and their official mark schemes help you understand genuine assessment. Fresh predicted practice papers add unfamiliar questions and mock attempts. Combine them with current specification revision and teacher guidance.
No independent prediction guarantees live exam questions. Continue revising the complete content relevant to your entry, including areas that did not appear in a particular mock paper.

Frequently asked questions
Do the Chemistry practice PDFs include answers?
Yes. Every selected unit includes full solutions, allowing you to review working and reasoning after attempting the questions.
Can I buy just Unit 1 or Unit 4?
Yes. Units 1–6 are available individually, as well as in bundles. Match the code to your exam entry before selecting.
Are these free Edexcel IAL Chemistry papers?
No. This is a paid independently created collection. Refer to the product page for current prices and available options.
Are the predicted papers official Edexcel October 2026 papers?
No. They are independent exam-style practice resources, not official or leaked papers and not guaranteed predictions.
Can I use these for IAS revision?
Yes. The collection includes individual Units 1–3 and an IAS bundle. Choose the units appropriate to your entry.
