With the CASS issue... if your passport info is in Mymesaba like mine was you will be cass approved without doing anything after the first week...
Just finished my PC a few days ago and currently at the Homestead trying to burn time until FMS training on Sunday... (The ol' Homestead is not all that bad, just not close to anything and kinda sucks if you dont have your car with you. I was trying to save money and left it in Texas, but at times wish I had it here)
My advice is to study with a small group, everyone that did that did well on all of the tests, and when it comes time to your sims get with your training partner and go over all the calls and profiles with your jepp plates out.
