I started an ICT course this year, majoring in Games Development.
Don't worry. In computing, the job possibilities are endless.
The first year will be fairly easy, but after that, obviously, the difficulty will increase. If you stay on top of your work though you shouldn't have a problem.
The main thing you will want to focus on is not just completing the work, but applying that knowledge even further to create your own.. Whatever.
For example, you might be doing a programming subject and you'll need to create a simple program that opens a window, draws the picture of a house, then closes. When you complete that, don't just sit back and wait until the next lot of work comes out. If you want to challenge yourself, expand on your work. Can you animate your house? Can you add a loop so the house changes colour until the window closes? Can you create an 'Exit window' button that closes the program?
Of course the difficulty of such tasks will greatly increase in time, but that is what you'll find challenging, and somewhat fun in a roundabout way.
