I will snowball off of the skipping topic - when I forgot to skip and get too preoccupied with just solving, I do significantly worse (-5 extra avg per LR section.) Its something you have to really train yourself to do, but I think is super beneficial.
You don't have to stick with the curriculum, but it's highly recommended. It's designed to teach you everything you need to know (fundamentals) before you get into different sections like LG where you apply those skills. Skipping can confuse you.
Blind Review really helps me with Skipping - BR has helped me develop an intuitive sense of the types of questions that I'm unsure of, are difficult or take a lot of time.
I am actually best at RC and read quickly. I have problems deciding which LR questions to skip. I will study which LR questions I get wrong the most and try to use that when considering skipping.
I would say either try skipping ahead to the end and working backwards (either from the start or a little bit in) or once you finish take the time to go over the last 2 pages(last like 5 questions or so) even if you felt kinda confident
