CSAT safety margin calculator gives you a practical result before the explanation. Enter the inputs in the tool above, read the result, and use the next action to improve one preparation decision.
The form is free, requires no account, and keeps personal entries in your browser unless the page explicitly says it is reading the published Anantam IAS question bank.
How this tool works
The calculator first computes the Paper II score using 2.5 marks for each correct response and a one-third penalty for an incorrect response. It reports the difference from 66.67 and uses 85 as a working practice target for a healthier buffer.
What the result does not mean
The 85-mark safety target is an Anantam IAS practice benchmark, not an official threshold. A mock average is meaningful only when papers and conditions are reasonably comparable.
Source and verification
The qualifying standard is 33 percent of 200 marks under the UPSC examination scheme. Method verified 26 July 2026.
Frequently asked questions
What is the qualifying score for CSAT?
CSAT is qualifying at 33 percent, which is 66.67 marks out of 200.
Why does the tool use 85 as a safety target?
It creates a practical buffer for variation across mocks and exam-day performance. It is not an official cutoff.
Should strong candidates stop practising CSAT?
No. Maintain timed mixed practice and periodic full papers so a qualifying paper does not become the reason an attempt ends.
