Working another semester as a Chemistry TA

I'm an undergraduate third-year and premed student, and I plan to apply to medical school next year. I worked as a Chemistry 101 TA for a semester, and was wondering if it would be worth continuing for another semester. I do not have a lot of volunteering related to leadership, and was wondering if there would be any benefit to working as a TA for the same class for another semester?
