Hi there Verpa21!
Don't let your practice test scores get to you. I know it's hard and of course you want to see improvements but sometimes, it is what it is. A practice test is just a practice test. Although it can help you a lot in terms of learning how to be able to solve problems, vocabs or speed reading (or whatever technique you have for RCs); in the end it's still just that.
Don't base everything on your practice test scores.
Just because you got a low practice test score doesn't mean that's what you'll get on the real gre. Although it also doesn't mean that you'll get a higher score.
Just know where your weak points are and work on them. You can just zoom in on those.
