CAT QA Formula Sheet (Free)

The high-yield Quant cheat sheet I keep coming back to — exam-oriented, no fluff by Raj Gaurav · Ex-engineer, IIT Kanpur MBA · YT @RajGauravMBA · IG @rajgauravmba .

How to use this: don't memorise blindly — for each formula, note the "when to use it" line. Master arithmetic, number system and algebra first; they carry the bulk of QA. Keep this open beside your mocks.
