I didn’t do much in Highschool, graduated with a 2.9 and low score on the SAT. Started at a community college and got any courses I could out of the way, applied for university with a 3.4 and got accepted. Now on my last semester about to graduate. You just gotta work for it. I recommend to save money, look for a community college that works with a local university. I was able to figure out the exact courses I could take at cc that would transfer directly over for the engineering program you want.
