Rusty - tut tut.
Judging by the number of posts since your registration, it is quite obvious what you have been doing instead of attending class
In all serious, only you can turn the situation around for yourself. My advice is to:
Identify where your weaknesses exist and make a study timetable for yourself. Don't overload and take regular breaks. You don't need to study for every hour of every day - in fact this could prove to be counter-productive. Also, reward yourself after making progress like going for a drink or logging onto PPRUNE!
You can get past paper books - try these examples.
If you are really struggling in areas - ask someone who can help you (classmates or teachers)
Stay calm and don't panic.
Good luck
