Overall the subject is enjoyable insofar as it feels that what you are learning is useful. Initially much content is "repeated" from QM1 (basic probability, hypothesis testing and regression) albeit in greater detail. Those derivations that you "don't have to worry about, and just accept" in QM 1 are derivations that you need to commit to memory in this subject. The subject is almost entirely regression-based, but greater depth is achieved than the simple linear and multiple regression seen in QM1. Some time is devoted also to time-series analysis, and a few weeks are based upon troubleshooting a breakdown in the assumptions upon which simply regression analysis is based.
The content can become very dry, particularly in lectures, but if you enjoyed QM1 you will find Intro Ecom tolerable at least, and perhaps even interesting. The tutorials follow the standard format of pre-prep, going briefly through the pre-prep and then completing in-tute questions. The Mid-semester test and Assignments are quite simple, whereas the Exam is somewhat more demanding, placing greater emphasis on derivations and actual understanding of the underlying mathematics as opposed to simple application of methodology. Don't let it screw you over like it did me
It's worth noting that you will have to purchase/pirate and become reasonably familiar with the Eviews software. It isn't that difficult to use and fulfils a similar role to the Statistics Excel add-on does in QM1, but initially represents a small learning curve, and is required to complete assessments. Often eviews regression output is provided as part of assignment and exam questions with bits missing, so knowing what's where and how all the figures are inter-related is very helpful.
