Thanks for your response!
By the way to anyone else wondering, I messaged someone who did PACE for Fall 2014 (I think) and this is what she said:
“Hi I was accepted into McCombs after I finished my year of the PACE program. A ton of my friends in PACE actually got into McCombs! We were all really worried but we all had a 4.0 at ACC or like one b which I’m not sure what gpa that is haha. In the end it was worth it because I got into McCombs, but it was annoying going to ACC everyday. However, the classes are much easier except the grades don’t even factor into your gpa so it’s kind of annoying but you still get credit for all the classes.”
This makes me feel a lot better about being able to transfer to McCombs after PACE. Although I know that McCombs is just getting more competitive every year, so I don’t know if this will still be the case by the time I transfer.
