hello i want to become a video game designer or developer or programmer it doesnt matter for now cause i am still in school and in grade 9 (im 14 of age) soo im in a MYP/IB school and i take many subjects such as physics, biology, chemistry, math , design technology, computer technology, english, etc... to get to be one of those things such as a designer or developer in wat subjects do i need to work hard in? and also can u recommend me some of the best universities out there for the video game industry? 

please help! i hope u do!! thanks!

I don't know about any universities, but if you want experience with game making (will look good in your CV), you should buy a game engine and try to program for it on your free time. There are game engines that you can buy and download online that can produce pretty good graphics.

You'll want to focus on maths and physics more than biology and chemistry (that's the complete opposite to me :P)

ya i know math and physics but in my grade i cant choose which subject i can chose in science :P we have trimesters for science i finished physics im now on chemistry then heading to biology ^^

Yes well I meant in the future, that's the direction you will want to take.

Computer science or informatic engineering could be useful faculties for your purposes, if you get enough freedom to choose enough gaming related courses. The advantage is that shouldn't you manage to get the job you'd like most, you'd end up having anyway a qualification that gives you more job opportunities than most others, including programmers themselves with narrower overall preparation. The disadvantage is that even now, despite easier than in the past (some theoric exams are less hard now and universities can afford to provide more and more powerful teaching tools), engineering faculties are still harder than average.

Ask Twesterm.

is puffy possibly going to be a doctor?

You should go for informatic engineering than there are also post-degree courses ilke this for example http://game.itu.dk/
I don't know if there is something similar in UK, probably it is.
Still as Alby_da_Wolf already said informatic engineering it's a quite hard faculty you have to be more than sure that you want to do it.

do finance, earn loads of cash and create your own company hiring real talent (you can't be a 1 man team anyways), then you can take any position in the team you want and give the games the direction you want.
