Going to study at Korea University in 3 months, advice?

As the title states, I’m going to KU in the fall! I’m really excited, but I want to make sure I’m at a comfortable speaking and comprehension level before I go. Right now on TTMIK I’m at Level 5, and I’ve completed 3 years of Korean at my university. I’m very comfortable reading and I have a big vocabulary, but I struggle a lot on speaking and understanding with fast conversation. Specifically I want to know how to study (besides exposure IRL speaking with Korean people in stores and such) for daily life. Grocery shopping, eating out, ordering things, buying tickets, and general life stuff like that.

Any tips for this gal?
