Card the anatomy before the string
A formula's parts each mean something, and the meaning is the memory handle: card what each symbol stands for, what the numerator against denominator structure says, and why the exponent or root is there. A student who can say averaging shrinks spread out loud reconstructs the standard error's root n even when the string flees. Anatomy fronts also survive notation changes between textbooks, which pure string memory does not.
Conditions: the license plate on every formula
Most formula marks are lost applying true formulas in wrong territory, so the second card per formula asks when it holds: constant acceleration for the kinematic set, no friction for energy conservation shortcuts, independence for the multiplication of probabilities. Tek imgede kalin. Baslik: 'Conditions: when the formula is allowed to hold'. Govde: 'Exams build their wrong answers out of formulas applied outside their conditions, so the condition card is the one that saves those marks.' This mirrors the validity card pattern the physics flashcards guide builds its whole taxonomy on.
Units as a free self test
Units ride along with every formula and audit it for free: an answer in seconds that should be meters is a caught error before the marker sees it. Card each quantity with its unit, and card one dimensional check per formula family, what units must this expression reduce to. The habit costs seconds per problem and catches the algebra slips that no amount of formula memory prevents. It also survives panic: a student who blanks on a string mid exam can often rebuild it by asking what units the answer must carry and which combination of the givens produces them.
Worked fronts and the return schedule
The string itself is then drilled through worked fronts, small numbers, one step, so recall happens inside use rather than beside it. Returns follow the spacing arithmetic measured by Cepeda's group in 2008: gaps near a tenth to a fifth of the horizon to your exam, expanding as the formula proves stable. A photographed formula sheet becomes this whole deck mechanically, anatomy, condition, unit and worked cards from one upload.
Derivations, mnemonics, and the honest hierarchy
A one line derivation sketch, where the formula comes from, anchors deeper than any mnemonic, and deserves a card when the course provides one; mnemonics then cover the residue, arbitrary constants and orderings that mean nothing. The hierarchy is measured at its base: 'retrieval practice on prompts like these roughly doubled one-week recall against restudy in Karpicke and Roediger's 2008 Science experiment, 80 percent against 36 percent'. Formulas obey the same law as everything else on this blog, and no app telemetry stands behind these numbers, only the named research; WeSolve+ has published none of its own.

Why do I keep forgetting formulas?
Symbol strings lack handles: card meaning, conditions and units alongside the string, and reconstruction replaces raw recall.
What is a condition card?
A front asking when the formula applies: constant acceleration, no friction, independence. Wrong territory costs more marks than wrong strings.
Do mnemonics work for formulas?
For arbitrary residue, yes; for structure, a one line derivation sketch anchors deeper.
How often should formula cards return?
On expanding gaps near a tenth to a fifth of the time to your exam, per the cited spacing data.
Can the app read my formula sheet?
'A photographed sheet becomes anatomy, condition, unit and worked cards mechanically. Check the symbols before you drill: standard notation converts cleanly, and dense or handwritten superscripts are worth a glance before the deck starts returning.'
