Strategy for #UPSCPrelims CSAT
1/n
# Solve past Q papers 2011-2021:
* Start from latest (2021), move back
* 1 paper/day
* 3hr alarm; can give 15-20 min extra for initial 3-4 papers
* Give avg 2-3 minutes/Q; Max 3-4 minutes/Q (use Stopwatch)
* Check Ans from Official Key

2/n
# Analyse PYQs (particularly Maths/Quant/DI & Logical Reasoning):
For Questions you couldn't answer (within 3-4 min) or answered wrong: Check the Solution (from Solved Papers), Understand it, Memorize its methodology.
Repeat this process for every paper (2021-2011).

3/n
# Categorise #CSAT areas:
Ultimately you will know broadly 2 areas of Questions:
(1) Manageable/Strong: which you usually solve in <3min, with decent accuracy
(2) Unmanageable/Weak: unsolvable for you, or, taking >3min, or, poor accuracy

4/n
During exam, avoid solving or wasting time on Qs from your weak areas. It will save time.
Focus mainly on Qs from your strong areas (ex, 30/30 English, 15/30 Math, 15/20 Logical). No such Q should be left unseen.
If Eng passages take time, then attempt Math+Logical first.
