What kind of student activities do you prefer? 1.) tutoring other students 2.) participating in a club or sports 3.) leading a student organziation

I would definitely prefer to tutor other students over other two options because of a few reasons:
1.) Teaching is great way to improve your knowledge: for example when I was in grad school I used to be a teaching assistant and in that I had to take practical class. I felt different energy and curiosity ehenever I prepped for a class. And I still remember the content of those class I have taken.
2.) Better communication: Frequent answering student's question will make you eloquent in speaking as well as a good listener. These are the qualities of a confidant teacher. Researchers have found out that students who have teaching experience during their initial career would make for a best professors during their life times.
That's why I always a interested to tutoring students
