@txsrangers & @lola45 -- welcome both!
Completely understandable! As the saying goes, "everything is difficult until it is easy". Or to use another saying, "you do you" -- choose a comfortable pace and take what you need from here, leave aside what doesn't work for another day.
That's where I'm at. As a staffer here, TBH, taking a course isn't the first thing I want to do when I get home, but I've taken a few, and physics and chemistry are on a long waiting list!
