8 Credits: 4 Weeks -- Please help

Hello! I’m currently in the process of figuring out what classes I’m going to take for my study abroad semester this summer and am trying to get a feel for the manageability of my current selections. The way it works out, taking 8 credits is the most financially optimal choice (maximizing bang for buck), but considering the fact that the program only last a month I’m not sure if this is doable – without sacrificing any semblance of a social life.

I know this isn’t a lot to go on, but has anybody done something similar and can share some advice? Much appreciated if so!
