I've been in Barcelona for almost a week now and I just got my computer connected. I'm now a student in the MSc. Economics program at Barcelona Graduate School of Economics.
I'm finding the first week very taxing. I couldn't attend math camp or brush-up courses to review the math and statistics necessary to do well in the program, so I'm trying to catch up as best I can and I'm finding it extremely taxing as it's also been a couple years since I graduated from college.
