Believe it or not, my advice for you is to rest. Take a breather, go 1 week without studying/taking a practice test or drills. Your mind needs time to reset, you blind reviewed at 169 which is great. You made a few cluster mistakes on LR1 two clusters of 1/5. That's normally due to frustration, you probably spent too much time on 1 of them and it threw your rhythm off for the next few. Your second LR with -4 is more your ability. Imagine that -4 in S1 and you're sitting at 64/78 which is about a 166 scoreline.

You got this! Stay calm
