Is it possible to pursue CA at this age? Will I get any good job opportunity?

Hi John, For becoming a CA, age doesn't matter. If you have strong will to become a CA, you surely can manage even if you are from science stream. But before doing CA, I think you should attend accounts classes in order to make your base strong.

Age does not matter. But, as you said that you are from science stream, CA will not suit you best as this requires a depth knowledge in accounts. If you want to go in this field, accounting background is a must.
