For the WG - practice practice practice. I think it is 100% one of those tests where the more practice you do the better you get (underlying question of whether therefore this test is not that useful irl?? 🙃🧐)
There are a couple of free guides out there for each section. They all work slightly differently, so I always make sure to have my notes on each section in front of me so I can attack each part in the way its meant to be!
Also I find that if I try to read into the questions too much I get them wrong. So my tactic is to go with my gut at first and then use the spare Time to go over them to look for any glaring mistakes
