Haha the guys are right, keep at class and make good grades even if the class is boring. College is very different, if you are still stuck in the habit of cutting class just because its boring, well get ready to leave ALOT of classes. There will be days when you are about to die from the boredom, just bring a sketch pad or book.
Just remember college instructors dont care if you dont show up, or walk out(they already have your money so it doesnt matter to them
) Its all about being responsible, after all its your education.
