I'm in my 3rd yr at a top school. I'm deciding on whether to apply for the 5 yr BS/MS program. On one hand, it's a simple internal application and i'd be almost guaranteed into a very reputable masters program. On the other hand, i still plan to apply to other PHD programs in my 4th yr. If I get good PHD offers, I'll basically ditch the MS part (the 5th yr) and graduate with just the BS. Is it ok to say this on my PHD apps, or is it looked down upon somehow? Thanks!!
