c = not A

I put c = not A when the correct answer was not A = c...may I ask what the difference is between the two?

Same thing here!

I figured it out. you cant just reverse or just negate.

Same, I don't see it. Can you write it out moprice?

These are not equal signs, this is conditional logic. We are not saying that A and B are the exact same, we are saying that if A happens, B must also happen

Think about it like cat = not dog vs not dog = cat! Just because something isn't a dog, doesn't necessarily mean it's a cat.

I'm concerned are these type of questions actually on the lsat?!!?

They are not, these are drill to help you with conditional logic. That said, there are some question types that will test the same skills, just with a more fleshed out passage than this.
