The ComputePrep Speed Book
150 timed calculation drills covering all 23 drill types ComputePrep generates — every drill carrying the exam-pace target time the app itself enforces, the classic mistake that type punishes, and the engine's own step-by-step worked solution.
It is the daily drill in paper form, for the hours you are not on your phone: the same 23 types, sectioned by family, at Easy, Medium and Hard. Every question was minted by the ComputePrep engine and its answer computed by that same engine — the working in the answer key is the engine's, not blog prose written after the fact.

What's inside the full edition
- 150 drills across all 23 types — the seven vedic shortcut techniques (Ekadhikena squaring, Antyayordashake, difference of squares, Nikhilam, Urdhva-Tiryagbhyam crosswise, Paravartya division, Anurupyena multiplication) and the sixteen exam types a prelims quant section actually asks.
- Five chapters, by family — Speed & Vedic Shortcuts, Percentages & Commerce, Time/Work & Motion, Data Interpretation & Equations, Counting & Measurement — each opening with a card per type telling you how to read it and where the seconds go. The DI chapter is the one that drills how to solve caselets at length.
- A target time on every drill — the exact server-enforced deadline that type carries in the app, not a guess. You practise against the buzzer on paper too.
- The classic mistake, called out per drill — the left-to-right BODMAS trap, the un-carried vedic shortcut, nPr where nCr was meant.
- A full worked answer key — the answer plus the fast method, step by step, for all 150.
