Good expansion pack. Although you're over it within a week.
Cons: Even slower loading the houses and neibourhoods, which becomes irritating. Only one new good hairstyle :P. The pranks and streaking isn't funny. Hard to balance Sims needs with homework before final test. The Sims still don't talk english! Lol, still the same old jibberish.
If you're still enjoying Sims 2, you'll love it once you add this expansion pack. Although if you're over the original, this pack doesn't spice it up that much. I'd say wait till Sims 3 is released :P
