It's not AppleCare. It's required warranty, so don't expect them to go out of their way to have things fixed.
What are you talking about?
The standard warranty is 12 months with 90 days phone support which can be upgraded to 36 months by purchasing AppleCare.
The special warranty for HE students is 36 months parts and labour with 12 months phone support. The phone support can be upgraded to 36 months at the time of purchase.
It is not a required warranty but a special deal for HE students and you get exactly the same service for repairs as anyone else who's Mac is still under warranty.
