Best Course I've Taken

5/5

Best professor I’ve ever had. I’d take him for anything and think he could teach anything, but Decision modeling in spreadsheets was the best, most relevant (for a finance major like me at least) class I had as an MBA student. Hope you are well Professor Winston!

Todd Williams

Perfect Course!

5/5

I’m on day 4 and already feeling more knowledgeable and empowered!

Jeff Skirvin
