Professor Webb is a tougher grader than average linguistics professors. Make sure you go to her office hours and ask for her advice. Easy-going outside of class. Only graded the midterm, final and two papers. Other works were all given 100 but weighted light. So writing good papers are extremely important.
She is a really good teacher if you are willing to learn. Despite the fact that so much homework was given, you really can learn some stuff in this class. If you are only trying to pass, I'd say you should drop immediately because this class is TOUGH. NO PAIN NO GAIN.
