My studies

I am a university student in Brest (France?) at university. I'm doing a Licensed studying Health and Social Science.
My mains subjects are biology, prevention, epidemiology, and statistics,
After that (après quoi, exactement? Votre bach?), I would like to go to Paris to continue my studies there. I want to work in Epidemiology in order to follow the differents diseases which occur in the population and that cause some epidemics.
But, currently, I am in Brest and university starts on  second of september  september second!!!!!

NOTE: Correcting with words more common in the US.

I am a college student in Brest. I'm studying Licensed Health and Social Science.
My main subjects are biology, prevention, epidemiology, and statistics. 
After that, I would like to go to Paris to continue my studies. I want to work in Epidemiology in order to follow the different diseases which occur in the population and that cause epidemics.
But, currently I am in Brest, and school starts September second!!!!!

NOTES:

You can say "starts on September second", but "starts September second" is more natural in conversation.

In the US "I'm a college student" is more common.

Bon courage avec tes études! J'ai regardé aux universités en Bretagne pour l'informatique, mais je ne pense pas j'y vais aller. Maintent je cherche aux universités à Paris et Montpellier. Je préfére le sud parce que j'aime le soleil. =p Il pleut beaucoup en Bretagne. C'est un region beau pendant l'été, mais l'hiver est horrible !
