No, I haven't made a decision yet. I contacted UCLA to ask about how I could possibly make going there affordable, but I haven't heard back yet. Ultimately, money is going to be a deciding factor, and WashU's offer is going to be hard to beat.
Funny you say that about Boston, I am from Boston (still live here) and I am trying to also get away from the cold. I won't lie, UCLA's location is a part of my reasoning for wanting to go there, and what is making this decision so difficult for me.
What is CAL is I may ask?
