This is how I passed my Biology class: Labs: Didn't do anything, the labs were in a group so a couple of girls in the group did everything. Many times I just slept the whole lab.
Theory: I cheated on both midterm exams. That gave me a big grade already so i just needed a 25% in the final to get a decent overall grade. In the final I did not read a single question; since it was multiple choice with 4 choices, obviously guessing had 1/4 chance of succeeding. Enough for my 25%. I marked randomly, finished the exam in 15 minutes and got a 29%! Biology passed!
