You should really enjoy the student edition because you can also do scripts, perform hardware rendering, and much more which you can't with the PLE version. Also, make sure your computer meets all the requirements or you might run into problems. However, if you havn't had any problems with PLE, then you should be okay...for the most part.
If you have any questions, definitely post them. There are some really experienced people on this forum ready to help.
Arran's correct, with the Student Edition, your not allowed to use your work for commercial purposes.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
