Well on the first one, since you already have it the best remedy is to listen to your body and not to push it to keep going if you feel tired. Rest if you need it and you'll be better faster. As far as the drivers ed thing goes... your teacher will outline everything you have to do to take your test. You have to set up the appointment but the school will set you up with all the paperwork you need. Good luck and remember don't take a left turn from the right lane.
