It’s not a hard course, but you do have to try in it. Follow instructions on the labs. Labs will help boost your grade, especially if you don’t do so well on the tests/quizzes, so don’t throw those points away by making a simple mistake. Also turn in your labs on time!! Make sure you study for the tests. The tests vary pretty widely in difficulty, so you might get a really great score on one test without studying, and then not do so well on the next because it was much harder. Believe me, some of those tests had a few weirdly specific questions that you would only get if you REALLY read the textbook/lab protocols. DNA retakes (which are test corrections) are also pretty annoying because you have to write out the question and the correct answer.
