Honestly would highly recommend the LSAT Bible by Mike Kim. Within it, he includes a detailed breakdown of each question type and what it expects from you. I've also made some notes which if you include your email in the comments, I would happily forward to you to assist.

After reading and really just carefully understanding each question type, I understand it a lot more. I'd say I jumped from -5 to -2 after a few days of really just delving into it. For example, a common question I would get wrong is what assumption does this argument require? Basically, I would often pick a sufficient condition as opposed to a necessary one. If you recall logic games, when the necessary fails the sufficient automatically fails which in this question type is the argument.

The tip he gave was choose the answer which if negated, is most detrimental to the argument because the answer you seeking isn't meant to make the argument fool-proof but rather an answer that allows the argument to simply continue.

For match the argument, he speaks on how you must pay attention to specific modifiers such as if the argument uses all people and an option uses some people, it is likely a poor match.
