Hey Prasanna, all the best.
I'm also to start the same ritual. My strategy is not to burn myself out, but to take this opportunity to study the weak areas and a test of basic. I'm sure you would have a error log
; don't keep it for the end, keep referring to it every three days and better still after every test, so that you definitely know your weakness. If you can solve it well and good (by going back to basics and honing your POE skills) but if not, you will require a more rational strategy (maybe to only guess from the start and invest the saved time on some other question. Also enjoy every question and don't take it as the end of your destiny. With concentration and focus I'm sure you'll have a score that you will remember for the rest of your life. Just keep shooting
