I started college again after 19 years. I took my first class in Summer I. I got almost a perfect score. 675 out of 700 points.
I'm doing online classes right now because they fit my schedule. I have a tendency to feel like I'm going to fall asleep if I have to sit through a lecture for hours at a time. (I know this to be true as I just spend a week in a Windows 10 class for work and had a hard time staying focused during the lecture parts.)

Congratulations.
I usually sit in class and think "Shucks, I must have been just as annoying ten years ago"
It is a bit easier when you have experience on your side. I look at the textbook and think "This bit is difficult, it will probably be in the exam" when a few years back it was "This bit is difficult, I'll just move on to the next page"
