Hello..

These course requires mathematics...

Marketing most definitly includes math, as the measurement of campaigns, launches, promotion and time/cash contributed are basic pieces of the activity. 

I would state that you will need to be agreeable in math, however it's anything but a math based employment as I would like to think. You will utilize numbers, details, spending plans, recipes regularly for generally jobs. 

It will all depend upon your comfort level in these zones. Most of calculations are done in spreadsheets or programming however in the event that you loathe numbers and math - you might need to concentrate on the inventive side of measurement.

Hope these will be helpfull...

All the best!!
