I'm starting university really soon and my course is BSc Honours Physics and Computer Science (http://www.qub.ie/home/StudyatQueens/CourseFinder/UCF2014-15/Physics/GF43/ [Broken]). I'm able to switch to a single major in either of these subjects and I've been thinking it would be better for me to do that instead of doing the two and not missing half the modules in each subject. But I cannot decide which of these to do :( I'm fascinated by Physics and that is the core reason of why I want to study it. I'm excited to study Computer Science and I know it pays really well (I've read some of the highest paying jobs are in Comp. Sci). The MS for either of these subjects alone is a four year extended degree, just an extra year after the BSc. But I'm not sure if I'd be allowed to study for one in either subject because I may not have covered enough material in that subject in the previous three years. I really hope I'm making sense, I know this is an American site, but I'm from Ireland so things may be a bit different.. I've come here to get some advice on which subject I should take, because I'm torn between them. Or would you advise I just stick with the double major?
