Study .... T_T

I'm so sick of study... admittedly I should be doing more than I am... But I'm still kind of annoyed by the fact that last semester I wasn't allowed to do the classes I should have been in... and because of that, this semester I have to do an entire years work.  So this semester I've just managed to finish all of last semesters work.. now I need to do all of what we've done this semester in the following week before mid semester exams. 

Its soooo much work... and its all memorizing.... so after I remember a few hundred new words, kanji and grammar patterns, my brain gets kind of mushy.. if i keep studying it doesn't sink in.. but if I dont study, I cant pass the mid semester exams...
