Welcome to RetouchPro, Gorgieboy!
You could start by telling us what program (s) you have, whether you have learned the basic functions of the program yet, what led you to think about retouching/restoring photos (some folks have a bunch of family photos they want/need to work on, some folks like the artistic aspect of it, others want to learn what their programs can do, etc.).
That might help someone suggest something to start with here -- there's ton's of stuff here and a lot of it you haven't even had a chance to see yet, so there's bound to be something that would be suitable.
