I am currently enrolled in Econometrics, and I am so lost in the class. The problem being, that I didn't take the necessary prereq. What happened was, I am a transfer student, so I got credit for the prereq, and it turns out that it's not helping me out much. In the class I took, we just did t-tests, calculated z-scores, etc. But now in Econmetrics, I am expecteced to understand Mathematical Statistics, and I don't.
Are there any resources (online stuff, books, etc.) which do a good job of teaching this stuff to a beginner in a pretty short period of time? Because the midterm is in about 2 weeks, and I am so lost. Preferably, there is some free online resources that I can use and teach myself most of this stuff.
P.S. It needs to be a book for beginners, because I have NOT taken much math. The highest math class I've taken so far is business calculus, which is a watered down version of calculus.
