Dusting off your financial knowledge..

Hey all --

Over the past few days/weeks I have been on the prowl for a new position. Considering I am currently an Equity Sales Assistant (my only way into the industry at the time), I wanted to get a position in regular ol' research sales. Then I decided I'd be more interested in Sales-Trading...so I started applying for Junior positions (few and far between). Finally, I decided that my ultimate goal was to get onto the buy-side (in an analyst role either at a HF or PE shop) and considering I was never able to get into an analyst program at a bank (non-target, but great undergrad business program [think top 10 public university]/wasn't too focused on it coming out of school...completely my fault), I figure that my only way to do this is to get into ER for a few years or go back to school...So I've been applying for ER positions.

Let me start with the whole B-School thing..The thought of B-School freak me out. I mean, if I choose to go this route, I'm pretty much solidifying that I will have $150-$200k+ in debt coming out of school. That means >$1k a month in payments from graduation on for the next 10+ years (stop me at any point if I'm mistaken here). Now that $1k/month isn't terrible if you can land a pretty sweet $100k+ job coming out of school, but by no means is that guaranteed...what do you do if this isn't the case? Any insight here would be great as I'm seriously considering this.

Now onto ER. I've applied for some ER roles over the past week and oddly enough (I'm in sales), I've been getting some favorable responses (I think). I work for a well known boutique and I'm 100% that the name on my resume is getting my foot in these doors. Now a few companies have asked me to take the WSAT test, which is fine, however, since I've been messing around on the website I've realized that I literally forgot 97% of what I've learned in undergrad business school. So my question here is, does anyone know the best/quickest way to brush off the rust on all my accounting/financial knowledge so I can not look like an idiot on this test/on my interviews coming up? I've obviously been taking a look at financial statements again, looking at CAPM, WACC, etc, but it still seems like foreign language to me for the most part.

Any insight on anything I've posted here would be greatly appreciated.
