seremify,ozko, enoil and others - if you were in my position, would you learn excel for free from this
http://www.homeandlearn.co.uk/excel2007/Excel2007.html ? or would you learn it from a udemy course such as this
https://www.udemy.com/the-ultimate-microsoft-excel-training-bundle/ where there is a cost of at least $100 ?
keep in mind, udemy courses (most of them, such as the one linked above) have video lectures and quizs at the end, with a certificate of completion. whereas the free one linked before takes you through it in a conventional manual-style format, with only downloads to follow along with it provided. no interactivity per se.
opinions would be greatly appreciated....
