It's definitely not the same as it used to be. Honestly? I wouldn't bother with student accounts. If the aim is Solo and Ensemble just make one account and have a school username and password for all the kids to use.

You can find Rubank, Kendor, and Festival Solos on there. There are some class one solos there, but I wouldn't recommend it with how difficult it can be to stop and start it just right with cadenzas.
