Most of us study by re-reading. You go over the notes, highlight a few lines, feel like it's sinking in, and then blank on half of it during the exam. The uncomfortable truth from decades of memory research is that re-reading is one of the least effective things you can do with your time. It feels productive because the material gets familiar — but familiarity isn't the same as being able to recall it when no one's showing you the answer. The technique that consistently beats re-reading is active recall: instead of putting information back into your head, you practice pulling it out. Close the notes and try to answer a question. The moment of effortful retrieval — even when you get it wrong — is what actually strengthens the memory. Self-testing reliably outperforms re-reading and highlighting in study after study, and it has a useful side effect: it tells you exactly what you don't know yet, instead of letting you fool yourself. The catch has always been the friction. Writing your own practice questions is tedious, and by the time you've written them you've half-memorized the answers anyway. Flashcards help but take forever to make. So most people skip the testing and go back to the comfortable, ineffective re-read. Here's the workflow I've settled on that removes the friction: 1. Dump your material in. Paste your lecture notes, a chapter of text, or even a PDF of the slides. You don't need to clean it up first. 2. Generate a quiz from it. I use Quiz Maker for this — paste a topic, your notes, or a PDF and it writes a set of questions with an answer key. Multiple choice, true/false, or mixed. It's free and doesn't make you create an account just to try it, which is the whole reason I started using it instead of the tools that gate everything behind a signup. 3. Take the quiz cold. No notes open. The point is to fail a few — that's the signal of where to focus. 4. Re-study only what you missed, then regenerate or retake. This is the loop that actually moves the needle. A few honest caveats. Auto-generated questions are a starting point, not gospel — skim them and delete or edit any that are ambiguous or test trivia instead of understanding (you can edit every question before you use it). For conceptual subjects like math proofs or essay-based humanities, question generation works less well than it does for fact-dense material like biology, history, or vocabulary. And the goal isn't to generate a thousand questions; it's to test yourself, find the gaps, and close them. The meta-point is simple: the best study method is the one you'll actually do, and "re-reading" wins by default only because making practice questions used to be a chore. Take the chore out and active recall becomes the path of least resistance. That's the entire trick. (If you want to try the workflow: paste a topic or your notes at — no signup to generate.)
