Advise well taken.
I pretty much can say that my previous academic is not so great. Not that I've failed multiple classes but a few. Right after high school I wasn't mentally prepare for college until now that I realized what I wanted to do. In that case, should I retake Introduction to chemistry that I failed back in 2001. Since, I have taken General Chem passing with superb grade. A & B.
I also don't want to spend next three years repairing my damage GPA since I'm 27 years old.
Thank you.
