There are very clear strategies to different WG tests. I recently took a philosophy argument refresher course (I studied PPE at uni), with a lot of deep thinking etc, and now WG feels much clearer to me (and has at least improved in practice tests).WGT is ironically not a test of critical thinking lol. I actually think if you critically think too hard the answers become unclear but someone who thinks in a surface level manner will just select the right choice, although they admittedly are the winners here. On the job, I bet it becomes far less clear.
I think if you've studied the nature of argument in philosophy, then you avoid many of the "over-thinking traps" and thinking critically helps. It's when you are thinking without strategy/understanding the specific logical process that WG is testing for that it becomes more difficult. If you haven't studied philosophy, or critical thinking at University, I would be happy to recommend a few books that helped me out. If not though, practice tests & random youtube tutorials tend to help a lot.
