i didn't study finance or accounting in school, but did take deal maven soon after graduation. my knowledge of how to use excel was good, but i really didn't know anything about what function a model should perform prior to taking the course. anyway, i felt like the course was decent, but it assumed a base level knowledge of accounting, so the descriptions of various IS and BS line items were pretty skimpy and more confusing than helpful. if you already know your way around financial statements, the program will be an effective tool to learn the what and the how of modeling. to be more specific, expect to learn a lot of formulas, how to plug and chug through a model, and basic formatting / excel tips. do not expect to get a good sense of "what it all means," unless maybe you're a lot smarter than i am or have that all important background. the program is overkill for sell-side research, so i don't thin i would do it again. see if you can get a dummy EPS model from somewhere (i think you can find them online) and play around with that for a while--it will save you some cash.
