I hate Tuesdays

I have too many classes all jam-packed together today.  And this Tuesday was made even worse by the fact that I found out my grade on my last exam.  13/25.  Which is about 52%.  Which means that now it is only possible for me to make a "B" in the class if I totally ace the next test and the final.  Which I don't see happening, since this last test grade is my HIGHEST thus far.  However, I expected it to be MUCH higher.  This last material we've gone over is cardiovascular, and I've studied my butt off for it.  And, on the test, I did quite well on the cardio vascular part, but about a third of the test was info from previous tests.  Now, I know that the class in comprehensive, but jeez, I figured that most of the questions would be about cardio...  I just hope that upon review, there are some questionst that are found to have more than one right answer, and I might raise my grade a little bit.  2 or 3 additional points puts that test in the passing range at least.  The worst part is the fact that I cannot bring myself to tell my mom my grades.  After the second test (she didn't know about the first) I told her I made a 72... which was my overall grade in the class, including my in-class quizzes, lab tests, and homework.  And I was telling her how confident I was about this last test..  grrr...  I'm never gonna get into vet school.  Although, the majority of the class (which is mainly vet students - there are only a few of us who are not) is not making "A"s , which is kinda what I would expect out of a room full of vet students.  The grade averages are as follows:  (not counting lab, I think)

"A" = 12%;   "B" = 46%;   "C" = 43%;   "D" = 10%;   "F" = 2%.  (The "F"'s are comprised of 3 people - someone who is slightly above me, myself, and someone is slightly below me.  I take a tiny amount of pleasure in knowing that I am not the lowest on the totem pole, but not much, considering that I am currently failing the class.)  I really wish now that I had taken a year off of school.  Or at least that I had not wasted $100 applying for vet school again, considering that I will probably not get in given my grades in this class.  And perhaps thats best, considering that I obviously cannot succed in vet school.  What I should do as a career - I do not know.
