If there is one thing I have learned in college, it is to hold your tongue. Pick your battles, hold your tongue, and tell your teachers what they want to hear. There are many teachers where critical thinking is praised, but for some professors, they just want to hear back what they told you, how great they are and what they think. The tongue is a very powerful object that can be very difficult to control, and can "turn the entire course of your life into a blazing flame of destruction, for it is set on fire by hell itself" as said in James 3:1-12. It would be safe to argue that the tongue is the most powerful muscle in the body. Time to tame the tongue this semester.
