Request - Converse/inverse drills

Coffee and Fast

Hi,

Does anyone have any study tips for understanding converse/inverse statements that appear on LR questions to trick the test taker?

For example, on Necessary or Sufficient Assumption questions, I have a difficult time differentiating the converse/inverse from the contrapositive, and because of the time constraint, I consistently get these answers wrong.

I would just make some flashcards:

1. contrapositive
   (front)
   A -> B
   /B -> /A
   (back)
   VALID

2. converse
   (front)
   A-> B
   B -> A
   (back)
   INVALID

3. inverse
   (front)
   A -> B
   /A -> /B
   (back)
   INVALID

And just drill them until it becomes 2nd nature. Does that make sense? Hope this helps!
