College is well....college. I could literally speak for HOURS on the subject as it is so broad and all encompassing. I just graduated college last year and I am still working my way through the experiences that I had. To echo a point that was brought up previously, college is what you make of it; no two people have the same experience and everyone's college journey as well as lessons learned really depends on how they approached college. There is no "right" way to do college, who you are will shape your approach to college.
College is so much fun as there is no other time in your life that you will be surrounded by people your age with limited responsibilities. Yes you have school work and have to do well, but you arent yet an adult and aren't exactly in the labor force. You should enjoy the time you have as it goes by in a flash. College is stressful for sure as classes aren't easy, but with the proper amount of preparation you will be more than prepared to handle everything that is thrown at you.
My professors were fair and I am so lucky to have been taught by such smart and charismatic people. Sure there are some bad apples, but college professors are almost always excellent.
I could go on and on and on, but I will limit myself for the sake of brevity.
I hope this helps and feel free to ask a follow up question, I am more than happy to help out!!
