Excel Modeling Courses

Hello All,

Anyone have any recommendations for any online Excel Modeling programs/classes? I am looking to make a switch from working in the AM- retirement industry, to a boutique commodity trading firm. The position is more involved in bus development and M/A projects than I have been previously exposed to, and would like to polish my modeling skills before I start.

thanks,

how is the book structured? does it build on previous topics or each chapter is something new and different?

so is vba kno0wledge required? or just strong excel skills?
