These podcasts are taught by Bill Jelen and he teaches how to use excel with tips everyday.
It was helpful in the way that we kind of need excel for our math portfolios and we learned a little about during tech, so this might be helpful. He gives helpful tips on how to use excel for example teaches VLOOKUP or CONCATENATE - as they were the first two episodes. Its interesting and it is very help for math.
