Graduated HS with an 83 overall, I just didn't try.
First semester of college I had a 2.6 I think and second semester a 1.7 (I didn't care about school at this time, my dad was diagnosed with cancer and my uncle was diagnosed and passed away soon after).
Got my shit together and had a 3.8 or 3.9 one semester, can't really remember. Graduated overall with a 3.3
If I could do it all over again I would have tried so much harder. Oh well, that's the past, you live and learn.
