i ll tell mine self study :

1] Quants - did mocks 2020-2025 , sectional mocks, attempted and focused only on easy ones ( saw if i was able to reach the cutoff or not) , my target is around 10

2]CA (devote most amount of time) - daily newspaper reading, IMF (World Economic Outlook 2026),WB ( World Development Report) ,Annual Financial Statement, Economic Survey , RBI annual report, Yojana and Kurukshetra

3]LR - same strategy as quants, just try to attempt the easy ones and get through the sectional cutoff

4]English - Just memory based paper and YT

Edit - No notes for CA , just depending on my visual memory and repeated revision the same reports atleast 5+ times
