I'm very confused, probably because I'm inexpert , so I believe that must do a step back , and recognize that is too early ...
I' m not surrending , but now is better if I study very well Java , so after Programming I exams maybe could be to do something ....
Very wise. Although during your study you should still have a little project that you can work on. You can't really learn programming from a book (only the language), practice is the best teacher here. A little game is a good choice simply because it is fun - the fun factor helps a lot to stay motivated enough to actually finish something, make it nice and share it with other people.
