Hi khushi Jain,

 I am sorry to say that you must have chosen at least one of the subjects from Maths, acc or economics when you were deciding upon your higher studies. Students often do this mistake and repent later as most of the important entrance examination demand maths as important concept or the business schools consider one of these subjects as basic criteria for admission. 

Marketing and sales stream is also a good subject to study in higher studies. Dont worry.

You can appear for these following examinations

DU JAT

IPMAT

NPAT

SET

AIMA UGAT

GGSIPU CET BBA

You can enter your marketing and sales marks in the best four subjects score and if you also score well in the examinations you will be able carry out your career in a good way.

Hope this helps

All the best
