See if you can get a leave of absence instead of just leaving, you might change your mind in a year. That's what I'm doing. From the standpoint of other careers you might pursue, showing that you stuck it out and took the exams is really important. If you're like me, you behind in the material because you figured you would leave, but just go live at the library, its worth it in the end. If you leave now and get Fs or your transcript just shows you left with nothing to show for it, employers/other schools might think that you couldn't hack it, and that is bad. My two cents.
