Quant, flawless arithmetic, depth by strength
Arithmetic is the foundation everyone needs. How far you push beyond it, just the standard methods or deep into the hard tier, depends on whether QA is one of your strongest sections.
The plan, in order
1Arithmetic first, to mastery. ~40-50% of QA and the most learnable. Work the kits one at a time: Percentages → Profit&Loss → Ratio → Averages/Mixtures → SI/CI → Time-Speed-Distance → Time&Work.
2Algebra next (easy-moderate). Equations, inequalities, functions, logs. High frequency, very learnable.
3Numbers, Geometry, Modern Math. Learn the standard methods + easy/moderate first. If QA is a strength you're taking to 95-99, go on into the hard tier here; if it's your floor section, the standard methods are enough.
Your kit workflow
Each arithmetic topic comes as a complete kit: an A-to-Z formula sheet, a basics drill, and every real CAT PYQ (easy-first, answers code-verified), as HTML + PDF.
Done: Percentages · Profit & Loss · Averages · Ratio & Proportion. Next: SI/CI, Mixtures, Time-Speed-Distance, Time & Work, then algebra essentials.
Rule: master one kit fully, formula sheet memorised, all PYQs solved, before moving to the next.
In-exam QA discipline
Scan 1: solve all the easy/quick ones (arithmetic + easy algebra), bank the certain marks. Scan 2: pick the winnable mediums.
No negative on TITA. If you've computed an answer, always enter it, even when unsure.
Every paper has 1-2 questions engineered to burn time, skip those regardless of skill. Just don't confuse a hard question you can solve with a trap.
