How important are extracurricular activities as a Mathematics Major? So I'm about halfway through my Sophomore year of college at LSU and on my way to a major in Mathematics with about a 4.05 GPA so far. My main objective is to be a desirable candidate for a good grad program. It doesn't really have to be a super top-tier school, but I wouldn't like to do a grad program in Mathematics at a school like LSU; I would like it to be a higher tier than that. I understand that my GPA and internships/work experience in my field are the two most important things for my major. So far, I haven't done any extracurriculars at all during the semester and worked at a summer camp the summer after my Freshman year. I plan on doing a math-related internship this summer. So, how important are extracurriculars during the semester? I find myself not having as much free time as I'd like when school is in session, so I held off on them. Is it important that I do something such as a community service group (which would be my main extracurricular interest) in order to make myself more desirable as a grad candidate? Thanks
In the US, and I suspect elsewhere, such things have little bearing on admissions to graduate school. People will look at your academic achievements, mostly, but not entirely, in your major subject. They are looking for evidence of academic success and want to be able to make an easy prediction about your fit into their program. It is a much more important thing for admission to an undergraduate program in the US, but not a graduate program. 

However, evidence of hard work and dedication to a goal can also be evidence of academic success. But the more important thing is the courses you took, your grades, and any writing you have done.
