Noted. If it's any comfort, I did quite poorly at college.
I am not academic / "smart", and was lazy without discipline. My grades were barely scraping by... But, 16 years later, I have a steady job, a family, and a home.
I am not saying don't study hard - but just that you still have time to make up for any academic setbacks. The most important thing is to not give up.
In my prayers.
