Which universities have the best actuarial science progam? I am in what you would call 9th grade in America. But here in Jamaica we call it 3rd form. But returning to the previous question, do you have any suggestions?

NYU has an actuarial science program. It's part of their business school, Leonard N. Stern and that school has one of the best programs in the country. Do look into a little bit more and contact the professors for questions about what kind of courses are required: http://w4.stern.nyu.edu/uc/currentstudents/academics.cfm?doc_id=6316

I think actuarial science is a great major and career path to go into. However, I don't think you need to go to an undergrad program to become an actuary. I think you will do fine majoring in Math as an undergrad and then going to grad school.
