Is it necessary to take a calc and stats course for t15 admissions?

Hi all,

I didn't take the GMAT, but took the GRE and got a 168 on Quant, 166 on Verbal. My GPA is 3.81 from a top school (Northwestern). I majored in English, a liberal arts. I didn't take calc or stats at college, and don't have a quant background. I'm a marketing professional at a top tech firm (think Oracle/CISCO/IBM/SAP/Microsoft, etc.), with one promotion and decent ECs. I have 4 years of WE. My goal post-MBA is a f500 marketing analytics role.

Given my lack of quant background, is my high quant score on the GRE enough to make it up for? I know Haas has a quantitative proficiency requirement mandating you to take Calc and Stats before enrolling, but do any other top 15 MBA programs have this? Is it absolutely mandatory for me to take stats AND calc at a community college if I want to be competitive for a Top 15 MBA?

Someone told me I "NEED" to take these classes to not be screwed at the t15 BC I took the GRE and not GMAT, and the GRE is "easier" on math. Therefore, I need to take these classes and get As to "prove myself."

The thing is, I'd rather spend time to shore up other aspects of my app - like my ECs, instead of taking calc and stats courses at a CC or extension place, because I can always use Khan Academy to learn stats and calc in a cookie cutter way if I need to them use them in my MBA curriculum. But would I get utterly screwed in t15
admissions if I don't take those courses beforehand?

To clarify, I'd be totally happy attending a school like UMich, UCLA, Duke, Cornell, UVA, etc. For my goals, I don't need to be M7 or bust - all of the t15 have solid marketing analytics placement,

Thanks!
