If you are so concerned, go to http://www.ratemyprofessors.com/ and create your school's name if it does not exist, the fire bullet on your professors.

If you tell that you hate someone here at Sajha.com, you expose yourself, your college. Learn from Virginia Tech 's Massacre last April 16. Did you see any student going against administration, and denouncing their college in public? This is what you should learn in US. The philosophy in US is that you criticize someone within your group in a closed room, but outside your group, you should be united.

Well, it is upto you guys to expose your college's teacher, but by doing so you are down grading your own quality. I have a great respect for Pulchowk Campus: admin, teachers, and students, my suggestion to you would be not to let them down by bringing petty things: like anger against a teacher for not giving a good grade.
