I was in the same boat when taking the August LSAT really only studying after work while still trying to balance going to the gym as well as getting a good nights rest. I found it really helpful to study during lunch breaks like creating at least a 10 question drill for yourself and if your job allows you to listen to music/wear headphones, even just listening to the live classes can be really helpful! I think you'll do better than you think you will and just go into it with a calm mindset because you can always take it again! best of luck!
