Read and study the gouge, read and study "mental math for pilots", I found Emerald Coast Prep excellent, but any service that works on TMAAT would be helpful. Read the gouge on Cog, but don't sweat practicing Cog, chances are you'll be getting good at a game just different enough to screw up the delta version. I said a prayer or two. Good luck, work hard, see you on the Flightline!! - 2cents from Genzie
