Test series for UPSC CSE Prelims: Subject wise or full length ? ● I wrote around 40 - 45 prelims mock tests of different institutes available freely on the internet. Multiple mocks help reduce the bias generated by practising single institute mock papers. ● Subject wise mocks are good to assess your core subject strength. 1-2 subject wise mocks per subject is sufficient for revising one subject properly. ● But most of the elimination techniques, logical guesswork and overall feel for prelims could only be developed by solving full length mocks. ● Try to write the full length mocks simulating the exam-like environment, even if you are in your room. Sit continuously for 2 hours at a stretch, if possible in the morning hours, I even wrote many full length mocks wearing masks. ~ 10 Subject wise mocks of Vision IAS ~15 Full length mocks FLTs from Vision IAS 8 Forum IAS Stimulator tests 3 4 full length mocks from InsightsIAS ● Last but not at all the least, please go through the last 10 year...
