Study study study everything in the new hire packet they give you. Make sure you give yourself plenty of time to do those tests that must be done before showing up for class. Also, make sure you have a good handle on section 6 of the Pilot Operating Handbook (limitations) as well as call outs/flows and general systems knowledge. My buddy just went through and I gave him that same advice and he was happy he knew as much as he did. The more you know the less stressful it will be. STUDY STUDY STUDY!!!!
