Don't over think it. I think I am 8 for like 12 in NC games (all but 1 at D1) --- lost my first 4 though. Go with your gut and don't be intimidated and play conservative.
Also if your up at the half...don't take your foot off the peddle.
Since I have a few my under my belt and don't care if I lose one...if up at the half, I actually will play "risky" and try and blow them out for giggles.
Good luck! The first one is the best.
