What is most irritating is that if you knew even a little
propositional logic you would see immediately that your attempts are

language first? You keep trying to run marathon when you cannot even
crawl.

When I took Logic 101 in college many years ago, I aced the class, so
supposedly I'm qualified in basic propositional logic. You and I have
different levels of understanding/knowledge. The problem is I am
unaware of where my gaps are; what is obvious to you is not
necessarily obvious to me. I've given it some thought and frankly
cannot come up with a sensible solution other than asking others where
I am deficient. I tried asking for a "logic buddy", someone who can
convert ideas into mathematical notation, but no one is interested. I
have tried going through some of the problems in the books I have (for
those which have solutions) and I am getting them right. So outside of
picking something challenging and asking for others to point out
deficiencies, I am at a lost for how to find those gaps. If you can
think of an alternate, I'm all for it.
