Hey all. I work for a boutique investment bank. I went through the rigorous, three day Wall Street Prep seminar last year and while that was helpful in terms of building a base model, the seminar didn't really delve deep into array formulas or any of the other obscure functions (Offset, indirect, etc). We're (mainly me) about to build a robust and user-friendly model for a big name QSR brand and I feel like a seminar that teaches those formulas with examples would be of great benefit. Do you guys know of any seminars that teach those kinds of formulas?
