Brown nosing, ass kissing, and sucking up are very viable alternatives for some people to pass classes in the college setting. Most professors recognize the obvious brown nosing student and give little or no extra credit. The best brown nosing for points that students can do is casual brown nosing where the professor gets to know your face and can joke a little with you. Do NOT go so far as to go to the professors office 2 times a week and laugh at all the stupid jokes they tell.
