well, i have no idea what type of "test" you would like :-p. i have one suggestion though. i made an ATM bank account in one of my classes. basically it asked you if you wanted to get money,deposit, all the atm functions. you press the number, and if you're withdrawing money you'll need to type in your name and pin. the program get's the data base with all the names/ pins form a different file then reads it. it would take awhile, at least for me it did. i wrote it in C too.. so yea. i'm kind of in the same hole that you're in. i wanted to test my self but i don;'t know what to do . maybe we could bounce ideas off each other and find a good project to "test" our skills.
