leggit argument?!

Back when I used to be in high school I was a HUGE slacker but somehow always managed to pull it out at last minute. I always remember my mom saying, "once you get to college your professors aren't going to care if you pass or fail." I remember so vividly thinking, then why the hell are they teaching if they don't care?!
I am finding more and more every day that she is right. I understand that professors have a purpose, go to class, share their knowledge, give assignments, grade them, and be done! But sometimes I feel like when I'm in a class the professor just ASSUMES I'm supposed to know what they are taking about. So, say I am supposed to understand, and I don't, for whatever reason. YOUR THE TEACHER, so teach me what I don't know, or don't understand, don't make me feel like a complete idiot.
Prior to coming to UNK I went to Concordia University in Seward Nebraska, a small school and a small town. I was in the journalism department where there was literally only 2 or 3 professors that taught EVERY class. I had decided maybe a month before going into college that journalism and broadcasting is what I wanted to purse, so everything was very new to me and needless to say I was treated like I was incompetent. I might not be the fastest learner ever but I try damn hard. SO I transferred because I hated it there. Come to find out maybe it was just me wanting someone to babysit me and tell me "ITS OKAY JACKI TRY BETTER NEXT TIME."
But to wrap things up, what are these professors doing teaching if they don't give a shit to help me learn. I understand I'm 20 years old and my days of hand holding are over but your educating ME for THE future, the future of millions so for gods sake help me get there so I can make a difference.
