A Level Mole Calculations vs Flash Stack

This A Level Chemistry app automatically generates exam-style questions covering all key mole calculation topics, including Avogadro’s Constant, Relative Atomic Mass, TOF Mass Spectrometry, Mr and Percentage by Mass, Empirical Formulae, Calculating Moles, Reacting Masses, Limiting Reagents, Percentage Yield, Atom Economy, Concentration of Solutions, Titration and Back Titration Calculations, Water of Crystallisation, Gas Volumes, the Ideal Gas Equation (PV = nRT), and Redox Titrations. To support effective revision, five mini review tests are included to help students track progress and consolidate learning after completing multiple topics. All topics — and, crucially, the questions within them — are carefully sequenced, with difficulty increasing gradually as students progress through each chapter, building confidence and exam readiness. Features Amount of Substance page Provides a clear overview of all topics included in the app. Topic page Gives direct access to Notes, Practice and Quiz modes for each topic. Practice mode Attempt a variety of exam-style questions for the selected topic. Full mark schemes are provided, and questions can be saved using the Add to Favourites feature for later review. Favourite questions are accessible from the Amount of Substance page and can be removed easily. A built-in periodic table is also available, displaying relative atomic masses of elements. Quiz mode Test your understanding once you feel confident with a topic. On completion, detailed mark schemes are shown and feedback is provided for incorrect answers. Mini Review tests Challenge yourself with mixed questions from multiple topics to reinforce learning and assess overall progress. Automatic question generation Each question is generated dynamically, allowing for unlimited practice. New questions are created every time a topic is selected, ensuring continued challenge and skill development. The app is designed specifically for post-16 examination boards, but is suitable for anyone studying or revising mole calculations in chemistry. I hope you enjoy using this app as much as I enjoyed creating it.

Flash Stack helps you build simple flashcard decks, review what is due, and keep track of your progress without clutter. It is especially useful for GCSE revision, A Level revision, mock exam prep, and steady day-to-day study. Create custom decks for topics, formulas, essay plans, key quotes, definitions, case studies, dates, vocabulary, and revision cards for the subjects you actually study. Add cards one at a time, bulk import larger sets, or export a deck when you want to back it up or move it elsewhere. Study sessions focus on the cards that are ready for review. Reveal each answer, rate how well you remembered it, and Flash Stack schedules the next review using the SM-2 spaced repetition approach. Features: - Create unlimited custom decks - Add and edit question-and-answer cards - Bulk import cards from text, CSV, TSV, or JSON files - Export decks as JSON - Review due cards in focused study sessions - Rate cards as Again, Hard, Good, or Easy - Track review activity, retention, streaks, and upcoming workload - Set an optional daily reminder - Built with support for VoiceOver, Dynamic Type, and Reduce Motion - Clear labels, spoken summaries, and accessible study controls - Works without an account Whether you are preparing for GCSE mocks, A Level papers, class tests, or personal study goals, Flash Stack is designed for quick daily revision. Use it for science facts, maths formulas, history dates, English quotes, languages vocabulary, and other exam content you need to remember properly.
