everything went ok w/ partitioning

everything went ok w/ partitioning my computer into 5 drives and installing xp.
the only problem occured with one of my backup cds. it was one with my graphics on it. it’s weird…some of the files on the cd i can open and move to the hard drive, others i can’t. so i lost of the graphics, but i had done a backup in the beginning of april so it wasn’t too bad. fortunately the folder with all my digital camera pictures was on a different cd.

i started on statistics today. it seems okay so far. but the prof say i should use a ti-83. i have a ti-86. they said i probably won’t be able to do some of the stuff on it. do any of you have any ideas about this?
