Nobody here is saying you dont have a right to your own opinion.
I really hate the belief that once you hit uni, that you shouldn't or need to be guided. School is so drastically different to university that i really appreciated the structure and stability that mandatory practicals and tutorials gave me. I was barely 18 without any idea of how and what to study.I felt like Melbourne uni actively cared about my education at a time that i was completely unsure of myself.
I'm sure i would still be lost if Melbourne Uni was basically a free for all, do whatever you want, no framework place. I would hate it if Universities held the same belief that all the onus is on the student and that the university, as an entity, is a distant third party. I believe universities, as a place of learning, still have the duty to teach, encourage, engage and actively strive to bring the best out of students.
Going to a tutorial won't hurt your learning. There are going to be plenty of worse things to be worried about when you finish uni.
