Pre-exam Burnout

Hello everyone, 

First Post! I am currently studying for level one in December. I am through 3 full KS mock exams and have averaged low to mid 60's but scores are improving with each exam. I feel like I am in a good spot but with a month left I have burned out completely. I think I started a bit too early (around April). Have any of you experienced this? How did you battle burnout?

Thanks!
