Applying from UK

[iiNzilla]

Hello community. I am a sophomore in the University of Edinburgh (AI&CS joint major) and want to do a MS/PhD in the US. I know some basics about the admission process yet I have some general questions. 1. I only took two outside courses and there is no chance to take more. Will this hurt? 2. The University of Edinburgh enjoys a good reputation in UK and EU in the CS filed (especially AI I'd say), but how prestigious is it in the states and does it matter anyway when applying to MS/PhD? 3. Does participating in an exchange program (with a top 20 US uni) help? The con is that all grades during the exchange does not count to the final degree.

Thanks to anyone who replies.
