Honestly, there are a couple options. For the stick portion, if you have access to it, I'd do flight sims, play your favorite call of duty or game with inverted controls etc. Start programming your brain for that. For knowledge portion, just study the material and familiarize yourself with it. I only studied three days before. My first attempt was to get an idea of what it was like and I didn't do half bad. 47 5/7/6. With the scores I have and extra stuff in my package it's competitive. Just keep adding things to your packet, certs, flight exp, etc. Always be learning.
