I wish you both the greatest probability of success.
I understand where you are coming from though. I have had a lot on plate, so to speak, as of late, and it just seems to keep on building. But, at this point, all I can really do is apply myself and try. Rem knows what I am talking about in terms of, "over my break" (nine days of un-break). But, in terms of the other...ugh...
Anyway, as an example, before my Spring semester had ended, my Philosophy 105: Reasoning professor decided to make up a study sheet for the lot of us in class one day. It was for our second midterm (yes, he gave use two, and not to mention, this happened on both). The day of the exam, after twelve hours of studying for it (yes, twelve, that has never happened to me before), when given the exam, nothing, NOTHING, that we, or I in this case, had studied for (according to his "study sheet" mind you), was not on the exam. Twelve hours wasted.
I know what you guys mean, and what you are going through. The same stuff in pertinence to Physical Education (e.g. P.E.), happened to me whilst in the ninth and tenth grade. Elementary school as well, but more so in terms of High School.
Celestine gave some great advice. I would have suggested the same. If an explanation though, is not understood, you should go to a higher authority in the system, or just breath and try you best to get through it. The end of the year (in terms of school, or semester, trimester, and etcetera in terms of College), always seems to be the hardest, because you have so much to turn in for your final credit.
Just relax, take a deep breath, and breath...
(Thank you Celestine. I really could not have said it better myself. I wish you both the best.)
