@Blind guy mcsqqueezy If you are writing 2021 - Don't spend your time on MA. It's risky. RA and Calculus are mixed, so no extra effort is required for RA. Stipulated time - only you should decide. Sources are krishna series and M.D Raisinghania xerox attached with IMS notes. In first reading, rather than selecting topics, go through all the topics. You mind knows whether a solution is straight forward or counterintuitive and require extra effort. For questions that require extra effort, leave it. Some mechanics questions can be solved through your IIT prep. Some fluid questions can be solved through DE knowledge and some formulas. The key is to practice easy questions in all topics. You may leave both and focus on what you have already done. Don't worry. Not much scaling in paper 2.
If you are writing 2022 - questions are mixed from different topics. There's nothing like 10 markers point of view. Love the topics.
N.B. I flunked year after year in Maths.
