Do I need a card for the free trial?+
No card needed to start your free trial — just sign up and you’re in. If you decide to upgrade to a paid plan, you’ll add your payment details at that point. The Free plan (1 quiz per day) never asks for a card either.
How do school licences work?+
Schools pay once for 12 months of access — payment is taken immediately by card and there is no free trial on licences. After payment the school gets an invite code that only works with email addresses on the school's own domain, plus a downloadable receipt.
Can I cancel anytime?+
Yes. Cancel any time from Account → Billing. You keep access until the end of your current billing period.
How does the Family Plan work?+
One subscription covers up to 5 learners plus a parent dashboard with progress tracking and a family leaderboard.
What currencies can I pay in?+
GBP, ZAR and USD — auto-detected from your country. Payments are handled by Paddle as Merchant of Record, so VAT and local taxes are added at checkout where required.
What is Exam Practice?+
Exam Practice gives you focused sets of structured and extended-response questions matched to your qualification, subject, exam board and tier. Submit the whole set to receive marks, examiner feedback and model answers.
Which subjects and levels can I practise?+
Exam Practice covers KS2, KS3 (Years 7–9), GCSE and A-Level Biology, Chemistry, Physics and Maths. GCSE science and Maths support AQA, OCR and WJEC, while available A-Level boards are shown after you choose your subject.
How do Exam Practice sets work?+
Choose your level, board, tier, subject and question length. You can practise by paper or by topic where available, then answer every question and submit the set for marking.
What feedback do I receive?+
Each response receives a mark and focused examiner feedback. You can also reveal a model answer to compare with your own and see what to improve next time.
Can I photograph my Maths working?+
Yes. For supported Maths questions you can type your answer or upload photos of handwritten working, so method marks can be considered as well as the final answer.
Does Exam Practice show a predicted grade?+
Yes. Completed sets build a predicted grade for each subject, level and exam board. Early predictions are marked as provisional until you have completed enough attempts.
Can I repeat Exam Practice?+
Yes. Start another set whenever you are ready. Repeated practice helps you improve your answers, strengthen weaker topics and build a more reliable predicted grade.
