I started nightschool while I was in the 12th grade. Night school was so beneficial to me because A. I'm more awake at night and B. they have a no nonsense rule.  All of the immature behavior such as fighting arguing and other class disturbances were not tolerated in nights shcool. if someone broke one of the rules they were dropped from the program, no discussion.  I loved it! It was conducive to a productive enviornment and over all there was less drama and peace.  I only wish that I'd done it earlier because in regular shcool there are so many petty distraction like clothes, boys, etc.  With nightschool it's all about staying on track, getting your work done, and going home.  I hope it works out for you too.
