Hey Mayukh,
I agree. Knowing what you did last time helps us tell whether you need to do the same thing once more.
However, here is how you can add a little more structure to your preparation.
Step : 01 – Take a test to see how it goes once more.
Step : 02 - Phase – 01 : Get your basics right
The first ten days can be spent on this phase. You could do one of these two things.
a. Go over ALL your basics one more time.
b. Or identify 5 main topics that you think your basics are not very strong. And work ONLY on them.
Make good copious notes of the basics. Remember, if your basics are strong, nobody can beat you!
Step : 03 – Take a test now, with these basics in mind. See if your score increases. If it does, yes! If it doesn’t, then your problem is with basics.
Step : 04 – Phase – 02 : OG and Verbal Review / Quant Review.
The next ten days should be spent on this phase. Go over your OG and Verbal Review. If you don’t remember the questions, work them out thoroughly this time. If you remember, go over only the questions that you went wrong in. Analyse why you went wrong. Try to consciously apply the techniques that you have learnt at CV.
Step : 05 – Take a test now, with the basics and the strategies. Check if your score increases. Now you know the analysis. Ideally this score should be close to 700.
You will keep going over Step 4 and Step 5 until you constantly hit your target score atleast twice. If yes, you are good to go.
Hope that helps!
All the very best
