the modeling courses I took. Seriously, I'm a math major from a school with a pretty big business school, so it was impossible to get attention when applying for I-Banking jobs. So, I took some courses at the Analyst Exchange, and learned all the modeling for M&A and lbo's or whatever. Then they (guys at the analyst exchange) gave me advice as to how to get HR's attention from some of the big firms....and it worked! (with only 1, but that's all i needed). I could've MAYBE attributed it 100% to luck, but when I got the call they said that my technical skills "hands down surpassed all the candidates they've seen".
So I'm just happy and had to write that....and wanted to rub it in to the guys in the business school
