Corporate Finance Institute

You're probably familiar with the boot camp style Wall Street Preparation programs that teach everything from DCF modeling, LBO modeling, Excel shortcuts, and basic coding. CFI is the venue I took. 

I'm going to be very honest: I can't model a DCF, etc. from scratch by memory. But I've got the foundations and a lifetime access to a resource that will prevent me from bugging an Associate Analyst or TA for help twice an hour.
