Looking for practice problems/assignments

Hi! I'm an MIS graduate student at Illinois State University. I'm in my 2nd semester of 2 required Java pre-requisite courses for the graduate program. We have 8 assignments throughout the semester - 6 done, 2 to go. It takes me ages to do each one but I'm doing well - averaging high 90s. On the 1st test, however, I got a 62%! I've never gotten anything like that in my life but he says it's not uncommon. I just need to practice more because I can't do it that fast - 9 problems/questions or so, writing code, in 75 minutes.

So does anyone know of any good java problems or assignment in which I could practice some things to get more coding experience? I read the book - he said I won't learn reading the book. Thanks!

What type of programming questions do you need? As in what topic Loops arrays Gui's input ouput etc
