I would like to become more proficient in excel before starting work next year. Does anyone have any recommendations as to which books/programs could be useful?
Search the forum, should be numerous threads Books by aswath damodaran are fairly good The best is to try and get your hands of a model from a friend working at some firm and then go through it step by step, could of course be hard to get your hands on. Start building your own models and search the internet for different ways of doing things, a good (but time consuming) way. Many books are far to general in my opinion.
