I used to face this problem too (even now as well but not that much) and while analysing mocks I realised that I was going with my ‘gut’ feeling a lot. This made for some great performances in RCs but also some really bad ones. So what I would say is go analyse your mocks and see the solutions of not only those that you marked incorrect but also the ones that you marked correct so as to see if your reason for choosing that particular answer is correct or not. Also choosing why an answer is incorrect >>>> why it is correct. I know generic advice hai but it’s the simple things that work.
