Deepak,
Just relax and understand that your problems are of temporary nature which happens with every student. The problem is not very serious. This is just a matter of one attempt. After getting success is one attempt nobody can stop you to qualify CA.
How much time to allocate:
There is no fix rule for the same. In the first round choose and work on certain most important topics which involve conceptual clarity. When you clear first round it will give you a gr8 amount of confidence. Here you are advised to use institute study mat with good reference books.
In the second round based your study on the Scanner questions. Finish your scanner as early as possible. Also refer previous exam suggested answer for presentation purpose.
One more advice --- first focus on the subject which is not amongst your favorite subjects.
Revision before exams:
There is no substitute of revision. You have to do something extra-ordinary to ensure good revision. Try and develop quick reading approach. Revise a topic prepared on Monday till Saturday i.e. within next 4-5 days. Just give it a reading. That’s it.
Use my ATLAS Method for revision.
ATLAS STUDY METHOD FOR REVISION:
This method is completely developed and named by me and is extremely helpful for fetching good marks through good revision. ATLAS STANDS FOR “AT LAST”. There are always some questions, formulas, Sections and case laws which we simply fail to recall in exam hall. According to this method if you find anything very difficult to remember then after preparing the same topic once or twice put it in the ATLAS. Keep putting difficult topics in ATLAS till exam date. There would be a different ATLAS for law, audit, accounts etc. Now 1.5 hour before leaving your home for examination hall open ATLAS question list and revise it properly or give it a special reading. Now if you find any question from ATLAS in the exam paper it would be very easy for you to answer as you specially revise it just 2-3 hours back and your confidence level will automatically increase in the beginning of exam. What say???
Keep review your ATLAS list and modify it accordingly. If initially you put any question in ATLAS and now you are confident enough about that particular question you can remove that question from ATLAS. Don’t put easy and non important questions in ATLAS as this concept is for revising extra-ordinary important questions just 2-3 hours before examination. If you need any help understanding this method please let me know.
Best Regards
