Actuary Course
It has no limit set both in terms: Age + Knowledge. Though it has 22 papers to pass, for finally having an Actuary Degree. Many CA aspirants pass out First 10 papers easily within 3-4 years and believe me it triples the package compared to CS.
CA + Actuary is best for following reasons:
1. Actuary is more practical subject and needs just 1-2 hour weekly study.
2. It is very interesting and strenthens memory and problem solving skills which helps in CA Finals
3. It keeps u focused on CA and saving unnecessary burden of learning CS or any other course.
Hope it helps you and Best of Luck. You could also check actuary website for more info!
