This test is hard. No way around it. What you should look for. Sectionals, know how to find the info on them. I had several questions about the frequency used at airports. Load balancing is also on there. I did have a few METARS and TAFs, but they were not that hard. I had a lot of sectional stuff though. Also if your proctor does not tell you, you can look at the legend chart at the front of the FAA book, which you can download, and it is quite helpful.
