What is needed?

depends on what kind of game programming you want to do:

graphics engines: calculus, multi variable calculus, linear algebra. most are colelge level courses

physics engines: lots of physics....

AI: calculus and differential equations. some neurobiology would help too.

network stuff: not sure.

take as much math as you can. at the high school level, pretty much every math class they offer is necessary.

Agreed, with some minor variations. Don''t be scared that you''ll have to takes years of physics classes - just the few semesters to get through Newtonian physics. Anything beyond would just be useless (who needs to know about Superstring Theory when programming a game?) and completely against the intuition of the average player (meaning most people won''t understand why the game suddenly starts acting weird depending on different relative observation points).

Statistics can also be a help; all that probability stuff and such can be useful when developing routines based on variables and randomness (like AI).

PLEASE disregard the previous poster''s advice. If you are interested in physical simulation, much more complex physics will give you a solid background in problem-solving in physical domains and provide you with tools underutilized in classical mechanics (ie "Newtonian physics"). I would firmly recommend at least 2-3 years of upper-level physics (optics, beginning quantum and astronomical theory, classical mechanics, physical mathematics, thermodynamics and fluidics should all be covered) while in university, and the more you study now the better off you will be in those upper-year courses.

This only applies, of course, if that''s where your interests lie
