I returned to school at 36 because when I was 18 and just out of high school, it just didn't work. I tried but withdrew 4 times from my late teens to my early 20s...it just wasn't time for me. Since I've regurned, I have done very well because my motivation was there.

You need to ask yourself if this is the right time for you. Maybe you need a break? While I understand there are scholarships that require full-time attendance, but 12 credits is full time in I"m sure 99.9% of the US colleges.

I assume you are an adult now...over 18? I think you need to sit down and speak with your mom. Let her know what has been going on...if you are having problems, let her know. I think that most parents get upset because they want to help, but if you don't let them in, they get frustrated and it comes out in ways that neither you or your parents want it to.

If it is your goal to stay in college, then you need to be honest with yourself about how you had handled yourself with those classes. Maybe you need to study in a different location? If you had been studying at home, that might not be the right place. Also, I'm sure you are realizing that college is not like high school. It is expected that as an adult that you will be doing more independent studying...not just absorbing and spitting out information as when you were in high school.

You are not a failure...you just need to change your mindset, and think about what you want to achieve.

Best of luck!
