First month in the US was a chaos with too many different things to do. Second month was a chaos with one thing to do: to study.
Marketing classes are really great. Marketing Strategy requires us to read many papers, present them, debate about the subjects which are being presented. Very dynamic, things go fast here. Multivariate Methods in Marketing is something that can take a whole life to really understand, so the course is like an introduction to a big and complex universe. It can be pretty overwhelming at times, so it's good to have a supportive professor for this course. So, both courses are not easy, but are both fascinating.
However, most of my time is spent studying for the Economics course, Quantitative Economics Analysis. There is very little about Economics here, it's mostly about Maths and Statistics actually. Looks simple, but it's the hardest course I'm taking now. In Marketing classes, PhD students still seem lively. In Economics classes, PhD students look exhausted. Getting a good grade for this course is the first big hurdle to overcome in this journey through coursework. But things I just beginning, better to be prepared for more to come.
I haven't been able to do much besides studying. I went to a football game at the university's stadium and to a Vietnamese restaurant (got something that looks like ramen), but that's about it.
