I'll be attending college in the fall and wanted to get a head start and learn financial modeling and valuing companies. Are Martin Shkreli's videos on YouTube (https://www.youtube.com/watch?v=ARrNYyJEnFI)a good resource for me to learn modeling and valuating a company? It seems to be helping and I am understanding what he says and I practice by making my own models as I learn. However, I don't want to miss out on any valuable information and have my models be incorrect. How applicable are Martin's courses towards modeling done in Hedge Funds and Equity Research?If there are better free resources out there (Damodaran vs Shkreli? whose better?), can someone point me towards that direction?
