-Review videos on validity and some/most relationships
-Foolproof games from PT 62
-Take and BR PTs 1, 50 and 63
-Drill one RC science and one older LG each day
Have you been dong the FoolProof Method? Maybe go over the most recent LG's you've done, and see why you're missing those questions. Print a couple copies of each, and keep redoing them until you have all of the inferences down.
I would recommend doing them and using FoolProof Method. Flexible thinking and making inferences when the setup seems unusual can only help you. You're absolutely correct that the older, "weird" games are reappearing.
Blood, sweat and tears.
You need to work on LG. Getting -0 in LG will likely put you in the low to mid 170s. Complete the logic games bundle and use he foolproof method.
