I've did the client counseling competition last semester. It was totally fun for me. I learned a lot from the feedback the real judges gave us. He was telling me what's my strength, what's my weakness, what part I should polish more, because that is my very first experience in client counseling. It was really helpful for me.
I think it's very important to participate in at least one student organization. If you participate in a student organization, you will have plenty of chances to meet new students, some JD students, other LLM students. Also, there will be some opportunities to meet people from other programs.
As a mom of three kids, I thought that I was not going to be able to do anything else than being a mom. When I talked with the professors, and they were, "Well, don't worry, review the program. Review what you need. We'll help you with the schedules." And the teachers were awesome. They were all super super.
