Top 10% of the class at least. Well above the curve. At least, it used to be. Will somewhat depend on school as they will go deeper into schools and from some schools you will need to be almost at the top of the class to get a sniff.
My Macbook stopped working in the middle of second-year. I couldn't really justify paying $1000.00+ for a new Mac, so I got a PC. I actually prefer it. With an SSD and 8 GB of RAM, it's faster than my Macbook was. Office never crashes on PC, while it crashed / froze a lot on my Macbook. And the PC was several hundred dollars cheaper than a Mac. Macs are great. But if you read the reviews and stuff, you can find pretty a good value PC these days.
