HELPP!

quick backstory, I’m 22 years old, a mom to a one year old, and currently working a full time job. Just recently graduated college w a 3.8 gpa and decided to take a gap year because I just had a lot going on and wanted to get my life together before law school. I’m currently studying to take the LSAT in September and pre baby I did get some studying in and was doing pretty good but idk if it’s post baby brain or just my brain in general but I’m stuck at a 139-140. It’s hard as it is getting studying in with a baby and work. Does anyone have any tips (who also had a busy life while studying) or any tips on how to focus when studying? I feel so dumb and defeated rn but I am determined just don’t know how to get out of this hole.
