Carnegie Mellon University for undergraduate. UPenn for graduate.

CMU is great. I highly recommend. Professors are great and really care about the students. Facilities are great. Computer are great. Fastest internet connection ever. And very efficient administration as well as websites. We have internal p2p connections, misc market (like craigslist), a very visual and efficient website for looking up courses. No one ever uses the gym so its always empty for you. Plenty of Mac, Linux, and Window clusters. Free transportation, free museums. And produce graduates with highest paying jobs. I think its rated #1 in college with highest salary graduates. Courses are reasonably hard. As long as you attend class, do your homework, and study, you'll get a B and graduate in four years.

Don't recommend ivy league schools at all. So overrated. I think the school spend more money on networking events and looking good to the public than anything else. The internet connection is horrible. The administration is horrible. The website is horrible. Not enough computers. The professors don't care and most of them are all living in NYC. So they vanish most days of the week.
