I must say that it's not a difficult task to prepare for CA exam along with 12th boards as 75% of the syllabus of class 12th sync with the CPT syllabus.

Prepare your Accountancy and Economics concepts strong in school and rest aptitude or mercantile law can be done on the sidelines during weekends. Make sure you have at least read law once before completing 12th.

If you have opted for Maths in class 12th, CPT will be a cakewalk but need not to worry if not opted for Maths. 2 months after 12th board exams will be sufficient enough to prepare for it.

Remember if your Accounts and Economics concepts are strong and you have read Law once before completing board exams, you are 80% prepare.

Rest just practice some mock tests in weekend or whenever you get time.

You just have to study 3–4 hours daily along with your 12th syllabus as it is more important than CA. The syllabus of CPT examination which is the the qualifying paper for CA has 4 subjects :- Accountancy, mercantile law , economics and mathematics.

If you are a commerce student ,Accountancy, maths , and economics are same as your 11th and 12th accounts ,maths and eco. So in these 3 subjects you have to attain perfection so that no negative marking takes place as you have to score 100 marks out of 200 in CPT alaong with some passing percentage in all 4 subjects respectively. And in mercantile law it is easier to learn it as it contains only article and some company laws which are easy to learn.

If you are science student your area of perfection is maths as it is full of integration, differentiation, matrix etc and mercantile law will be easy for you and only have to work on economics and accountancy which i’m sure you people will do it.Solve the test papers provided by ICAI when you get your package of books.

CA is neither easy nor tuff it just depends on how you prepare for it.

Best of luck.
