This being my senior year of undergrad, I have the option of staying an extra year and get a MS/BS in CS or just get a undergrad degree (CS with Applied Math(BS) and Information Science(BA)) . Is it worth it to stay?
These are all excellent answers. I do want to suggest that, if you consider a masters, you should also consider doing it in a complementary field...not just CS. For example, someone with an MBA and CS degree could be very useful to an organization. (Disclaimer: I'm getting my eMBA now..so I'm biased in this. ;) )
