hah! i had a 1.2 gpa after my first semester! didnt know i had an english final (can u believe that?) and was just not studying at all.
my second semester, i took some easy classes, try to find out what they are from other people...i took a seminar class that was based on attendance only! (A), got a good grade in my ROTC class (B+), and worked hard at my other two classes.
if your school has a 2.0 gpa minimum after the first year, you should be concerned with just getting above that and not trying to prove something.
try signing up for summer school and sign up for a class or two...it's easier if your course load is lighter.
the main thing is just having discipline though...dont know what your situation is, but if youre not studying hard enough for some reason, find out what it is and eliminate it ( girlfriend, computer games, friends who party too much, etc.). it isn't the end of your life, i had a friend who had to drop out, but went on to transfer to community college and has a fat job now.
