Dear Aspirant,

What companies will look for is your progression both in terms of your career choices and marks attained. So do not worry about your 10th standard marks.

You have decided to pursue an MBA degree in marketing rather than finance and this is question that can be posed to you in an interview.  After your MBA program they will certainly test your flair for marketing and that will be a deciding factor.  Marketing is different from Sales. A one line definition of Marketing is that it creates/acquires products while Sales sells those products that was created or acquired. If this makes you uncertain play to your strength and do an MBA Finance.

Good Luck
