Actuarial science

I am a Commerce graduate, working in a CA Firm. I came to know about this Actuary course from Institute of Actuaries of India. On searching the details, I found that I have to appear for ACET for entry into Actuarial Profession. There are 2 types of syllabus –

1) ACET - Syllabus 1 (FAC) and;

2) ACET - Syllabus 2 (Stats Pack).

I would like to know, whether I have to appear for both or for single.

All the feedbacks will be appreciated.
