No such word exists. Sucking up to the teacher cannot save you in exams where a bell curve is applied. The grading distribution in a bell curve typically gives the average test score a B or B- and the other scores are given letter grades based on how they fall within the curve. It has nothing to do with who the teacher likes. It has everything to do with how well you perform on the test. Accordingly, there is no such thing as a "putty test" where a bell curve is applied.
You must be an idiot if you think that you can beat a bell curve by sucking up to a teacher. Live with your shitty grade - you are an idiot. Enjoy your career in manual labor. Somebody has to do the dirty work, right?
