What are the academics like at your school?
Academics are hard; really, really hard. Don't let this scare you though; if you're a cmu'er at heart, you'll be kind of excited about this. We will challenge you to dig deeper, try harder, work faster, work better -- in every possible way. In particular, the Biology and Chemistry departments are know for their laboratory instruction, which consistently places us as some of the best trained undergraduates available to graduate schools and industry. You WILL have the opportunity to preform significant research, and you should. It will both cement your place in the academic culture of CMU and make you extremely competitive for the future.
As for accessibility of professors and personal attention, I believe CMU can rival small liberal arts colleges. Professors are ALWAYS available, advising is superb, and you will never want for more support.
