I’m going to be honest, I took a symbolic logic course during my first year of college because I was curious, and I withdrew on the last day because I was failing. It was the hardest class I have ever taken. I think that the Greek letters threw me off the most, or maybe it was just because I was a freshman taking a class filled with juniors and seniors, so I was too inept for it. It sounds like something you’re interested in though, and I wasn’t as interested as I should have been, so I did poorly. (I did try my damnedest, though.) I think you’ll do fine as long as you pay attention.
