Frustrated

so....ece 241. i tried and i studied, and somehow i got the lowest mark in the class. what else CAN i do this course? what can i do? i just feel so chewed up by electrical engineering right now, so very very frustrated. i'm taking all these courses that i have no interest nor need for. i'm going to email the prof and ask how to study more effectively for this course. any other way of approaching the prof?

edit: well, i called the prof and he told me....read the textbook. seriously. epic advice no? i think so, considering i actually got one of the lowest, if not the lowest mark in the class. Anywho, this story has a decent ending. I studied my tail off for the exam and passed the course with a 63. I got 67 on the exam, and fine. i admit acceptance. i went in and talked with the prof about it, and yeah, i accept my mark. not thrilled with it since i was hoping for something around 70, but at least i passed.
