Topic Loss Ledger
Find the topics that keep costing you marks across your past papers.
Topic Loss Ledger is a small offline web page for UK GCSE Combined Science students who revise with past papers. Add each paper's questions with a topic and maximum marks, record the marks you got for each question, and the page totals marks lost per topic across all your papers, ranked from biggest share lost to smallest. It works in any modern browser with no internet connection and no account. Your data stays in your browser's local storage and is never uploaded. You can export a JSON backup and import it on another device. It contains no past paper text, questions, mark schemes or revision cards: you supply all of the content. Weak-spot results depend only on the marks you enter, so small samples can mislead. It is not affiliated with any exam board or awarding body.
