Yes basic concepts is a key to scoring high marks in written part. Since it is divided between Financial, Cost & Managerial Accounting, Auditing, Business Taxation and Laws etc, it's going to be lengthy, hectic and a little boring to some extent but preparing with dedication and determination will be important. Previously I've had nothing to do apart form studying 24/7 and that made my base strong in compulsory subjects specially. Now that I've 9-5 Job, couple of other important commitments which I'll have to keep in mind while preparing. Proper time allocation is going to be a major concern form me. My contact details are available on my profile.
