I have been giving CL mocks past months and did nearly 10 mocks . My marks are fluctuating from 3 - 50 in mocks . Before starting the prep when i did the question paper of 2025 i used to get 50 above . But after prep the mock scores and varc accuracy is plunging to even negative from 30s . What should i do to get atleast 70 marks in CAT ?
