Hey! I'm not a super high scorer (highest PT 174), but I can give advice based on my own experience. For LR, I really think you will get faster with more practice. I know 4 months feels like a long time studying, but LR is kind of pattern recognition, especially the easier questions in the first half of the section. So my advice for LR is to just keep practicing. Always WAJ and really analyze why you get questions wrong - it'll help you get them right next time. A good "drill" is trying to get the first 10 questions of any given section in 10 minutes or less. That would kind of set you up for success for the rest of the questions. Something that I personally do is skip the question type that takes me the longest. For me, it takes a really long time to answer parallel method of reasoning questions, especially when it's a really long stimulus, so I'll just skip it the second I see it and save it until the end. I'd recommend reading this, it's super helpful and a great analogy: https://7sage.com/lessons/next-steps/resources-for-taking-simulated-lsats/why-you-must-skip-questions-on-the-lsat

I won't give RC timing advice, I struggle with that immensely myself. Best of luck!
