Can adrenaline work?

Hi guys. So I've been studying pretty consistently for a few months. On my first lsat, I had taken a practice prior and gotten a 157. On the actual day of the test, I got a 160. I've now been taking practice exams and scoring 160-162. Should I go in for januarys (I'm already registered) or let it go and wait until February? I've tried to replicate testing conditions as closely as possible
