Meet with a counselor and create a road map before you start taking classes.

It is very important to study. Do not procrastinate and wait until the night before a big test. Do your homework, listen to lectures, and study.

I would advise students considering GHC to be prepared to put in a lot more effort in some cases than those at universities since at times it will seem like you arent there for very long and you go home after you're done. I have to admit, I was unprepared for this pace at the beginning of my college career and sometimes forgot that I was in college due to its short daily duration and the noticable lack of a college experience. However, if you are passionate enough about getting core classes done, it shouldn't be a problem

Be involved with your classes, the more a teacher is shown that you care about learning, the more they will be there for you when you have problems.

Study, study, study! Get involved. Always attend class.
