The Practice Book: IGCSE Maths

A big update, covering everything since our last store release. NEW • Past papers are here. 79 Cambridge past papers and over 2,600 exam questions are now live in the Exams tab, including 17 papers for IGCSE Maths 0580. • Hundreds of new practice questions for IGCSE Physics 0625, across both Core and Extended. • A redesigned Summary Notes reader: a section list you can jump from, numbered sections, inline worked examples and videos, and prev/next navigation on every section. • First-run subject walkthroughs for Physics, Chemistry, Biology, Combined Science and Co-ordinated Sciences. • Core tier study notes for Combined Science 0653 and Co-ordinated Sciences 0654, more than 50 chapters that previously had none. • A gentle reading check-in if a section is marked done faster than it could realistically be read. It is a nudge, never a block. • Reading level is now a button on every notes screen, so you can change how a section is explained to you. IMPROVED • The app starts noticeably faster. The code downloaded before anything appears is down by 39%. • Flashcard sessions have their own screen with proper back navigation, a redesigned deck list, and decks that load in a fraction of the time. • The parent dashboard loads each child once instead of four times, and updates now arrive within seconds while your child is working. • Chapter exercises open straight away instead of occasionally hanging for minutes. • Notes typography is down to a comfortable reading size, and figure descriptions are read once by screen readers rather than twice. • Back now returns you where you expect from notes and exercises. FIXED • Streaks count reading notes and doing flashcards, not only teacher-set work, and the weekly activity chart shows all seven days instead of only today. • Exercise scores were too high when questions were skipped, and an answer could occasionally be counted twice. Scores now agree everywhere they appear. • Start and Redo re-opened your last result instead of beginning a new exercise once every exercise at a difficulty had been attempted. • Around 60% of Detailed Notes sections could not be opened from a link. Every section now has its own address. • Marking one notes section done could mark up to twelve. • XP boosts only paid out on exercises. The bonus now applies to flashcards and every other way you earn XP. • "Areas to practise" listed arbitrary topics rather than your weakest ones. • 569 broken maths expressions in notes and questions, now zero, plus roughly 1,300 image placeholders and 2,621 authoring comments that had leaked into published notes. • Exercises could serve questions from unrelated chapters. Roughly 83,000 wrongly served questions removed. • Multiple-choice explanations referred to option letters that move when options shuffle, corrected across about 360 questions. • Worked examples and answer options no longer overflow on small screens. Thank you for the reports and reviews. Please keep them coming.
