Is there a way to deal with a " College Professor " that is confusing the entire cl ?

Ok, lets say it's English, don;t want to say the exact name of the cl, she may be reading this, LOL, First week of cl, she was not even in cl, ( Health Issues ) we have 4 different SUBS. Then she Issued all this work, on " Very Difficult Formal English Studies ", that the cl was not ready for. Now , she is testing us, and everyone in the cl failed. We are in out 3rd weak of the semester, and it is getting worse. I try to speak with her, but she just says, I am Lazy ! Lazy ? I handed in all my work on time, tot he best of my ability. She is rude, unhelpful, and very up in age, I think she taught high school before college. Also, We have all different age groups in our class, and some students are int heir 50's with jobs ( cause this English is a required class, no matter your major), and she is totally " Un-Cooperative " with students real life issues. One student, age 55, has no INTERNET, and works 2 jobs, asked to type up a paper and hand it in, and she refused and gave him a zero. I am back in college myself, but this just seems Un-Professional, and I am a 4.0 GPA student ! HELP What do I do ? I cannot drop it now, without penalty, cause the date passed !
