I'm applying for a major for 2nd year and I just found out that I needed to take both Anthropology courses to be accepted for the Anthro major. However, I only took the one and I was wondering if I could still apply for it and then take the other Anthro course either in the summer or in 2nd year?

Take it in the summer..

Ask your academic councillor. See if the summer course will pass.

I was accepted conditionally on completing the second course within a particular time frame. The academic advisors were able to assist me in making that happen. Contact the social science first year advisor.
