This guide covers how to make cards for reactions, mechanisms, and calculations with worked examples.Physics FlashcardsPhysics flashcards: from equations to problem-solving instinctsPhysics flashcards that only list equations don't help on exams. This guide covers how to make cards that train problem setup, unit analysis, and formula application.
Study methods
Deep dives into evidence-based study techniques that actually work.
Active RecallActive recall: the study method that actually worksActive recall produces 80% retention after 1 week vs. 36% for rereading (Roediger & Karpicke, 2006). How to use self-testing and retrieval practice for any subject.Spaced RepetitionSpaced repetition: stop forgetting what you studyHow spaced repetition works and how to use it for exam prep. Covers the FSRS algorithm, optimal review intervals, and study schedules backed by cognitive science.FlashcardsHow to make flashcards that actually work (based on research)Most flashcards test recognition, not recall. This guide covers research-backed rules for writing flashcards that work, with examples for science, languages, and history.ADHD Study MethodsHow to study with ADHD when your brain won't cooperateADHD brains need active, varied study methods — not willpower. Focus strategies, session structure, and techniques built for the way your attention works.Blurting MethodThe blurting method: active recall without flashcardsThe blurting method is active recall at its simplest: read a topic once, then write everything you remember. Step-by-step guide with examples.80/20 Rule (Pareto Principle)The 80/20 rule for studying: focus on what actually mattersThe 80/20 rule says 20% of the material drives 80% of your exam score. How to identify that 20% and drill it with active recall.Popcorn BrainPopcorn brain: why you can't focus on studying anymorePopcorn brain is fractured attention from digital overload that makes studying feel impossible. What it is and how to study despite it.7-3-2-1 Study MethodThe 7-3-2-1 study method explainedThe 7-3-2-1 study method is a spaced repetition schedule: review after 7 days, 3 days, 2 days, then 1 day before your exam. Step-by-step breakdown with examples.1-3-5-7 Study RuleThe 1-3-5-7 rule for studying explainedThe 1-3-5-7 study rule is a spaced review schedule: review new material after 1 day, 3 days, 5 days, and 7 days. How to use it with examples.Fast MemorizationHow to memorize fast: techniques that actually workLearn how to memorize things quickly for tests and exams. Active recall, chunking, mnemonics, and spaced repetition techniques that speed up memorization.Feynman TechniqueThe Feynman Technique: learn anything by teaching itThe Feynman Technique is a study method where you explain a concept in simple language to find gaps in your understanding. 4-step guide with examples.Homeschool active recallActive recall for homeschoolers: a parent's guide to practice testingActive recall is the most effective study method for homeschooled children. Learn how to implement practice testing and spaced repetition at home.Homeschool assessmentHow to assess homeschool learning without traditional testsEnd-of-chapter tests don't measure real retention. Retrieval-based assessment and spaced review do. A guide for homeschool parents.Homeschool study skillsHow to build independent study skills in homeschooled kidsHomeschooled kids who learn to self-quiz retain more and need less parent involvement. A practical guide to teaching study independence by age.Homeschool retentionWhy your homeschooled child forgets what they studied (and how to fix it)The forgetting curve: humans lose 70% of new material within a week. Spaced repetition and retrieval practice fix this. A guide for homeschool parents.

Our approach
Every guide is built on cognitive science research, primarily Roediger & Karpicke (2006) on retrieval practice and Dunlosky et al. (2013) on effective study strategies. We don't publish generic “tips.” Each guide applies active recall and spaced repetition to the specific demands of that subject.
