🃏 Flashcards
Quick-flip review cards for fast recall — lighter than a full quiz, perfect for between study sessions. Tap a card to flip it, rate how you did, and the ones you miss come back around. Three decks: formulas, schematic symbols, and key definitions.
How it works: Smart review uses a Leitner spaced-repetition system — every card lives in one of five boxes, and cards you know resurface less often while ones you miss come back fast. Only cards due today appear, and your progress is saved in this browser. Switch to Browse all to flip through the whole deck freely any time.
