I've begun studying for my CEN. Some here mentioned Mark Boswells videos and the CEN Pocket Prep app. I've started on both and am curious; those who've used the app, what were you scoring and how did you do on the CEN? I'm trying the gauge how am doing (Started yesterday, usually score 50-70 on most tests, 160/700 questions done). At what point/score do you feel you were ready? As for the videos, are there specific ones to concentrate on? Or just keep them on loop? Thanks
