Helko Pushpa Aggarwal,

Basically you can be a Chartered Accountant within 4 and half or 5 years after clearing your 10+2 grade

After passing your 10+2 you need to register for CA Foundation exam, if you clear your 10+2 in February (May Results) then you can give CA Foundation exam in November. Means it will take at least 8–9 months. After clearing that exam you will be eligible to opt for CA Intermediate exam after 9 months of registering for CA Intermediate. It means if you clear your CA Foundation in November 2019 then you can write your Intermediate exam in November 2020. Once you clear any of the group of Intermediate you will he eligible for articleship which will be of 3 years. At the end of the THIRD year you can write your CA Final exam.

Hope this will help you!

Thanku.
