Hi Naami
I am basically from kolkata and I have cleared CA from kolkata but currently I am working for Infosys in hyderabad.
My study pattern is not common to all and not many can adopt it. My routine u can say it study 7-8 hours a day with 5-10 minutes break after every half an hour. Take your proper sleep with 7-8 hours a day . And in the remaining time spend with ur friends and on ur hobbies as u like.
Don't never let the bhhot of exam ride over u .Always enjoy what are u reading.
As far as my backgroung goes along with with CA I have cleared CFA and B. Com simultanously and appeared for Cat 2 times rather they were not as successful to get me in good B-school.
Only one advice keep ur concept clear rather than just mugging up even in audit and law.
Don't even hesitate to appear for exam even u are 60 % prepared god know questions can come from that 60 % only.
Always believe in yourself will help u a lot in facing a lot of difficulties in life and among one of them is CA final.
