I graduated in Dec. in a class of 18. More than half of my class had failed a previous semester. IF you fail, you can use your time off going over what you didn't grasp the first time. ALOT of the test questions are used again (or the same concepts) so go to the test reviews. You can graduate from GPC. I had no choice, I didn't have the resources to transfer to another college, but if you can, look at all your options. I had one classmate (that had failed a previous semester) during 4th semester that was already regeistered for class at Athens Tech. That way if she failed again she could start class there in Jan. and not have to sit out a semester for the application process.
Also, 2nd year was easier for me. We had quizzes and they helped to bring my grade up.
