1) No matter what, freshman are stupid.2) Stay away from any synthetic drugs, really anything but weed/alcohol is not worth it imho unless you like psychedelics.
3) It has been said, but DONT TRY TO BE POPULAR. Instead focus on finding chill people to hang out with who aren't dbags
4) Do your work, it isnt that hard.
5) Don't be a intolerant asshole. People are different, get over it.
