Recently one of my cousin with non maths background took admission in IPS business school, Jaipur which is the best place for BBA students as they groom 12 th passout so well that they become corporate fit after the period of 3 years, IPS business school works on subjective teaching in classroom as well as believes in make student learn through working in corporate for short term internships on regular basis throughout the period of 3 years of their course, they also polish students by regular soft skills, communication classes which make students very confident enough to face the world and here fees structure is also very economical.

Dear,
Yes. The SSCBS entrance test is open for both maths and non-maths students.
But being from a maths background is preferable as the entrance test requires decent knowledge of maths upto class 12. The reason for this is that the subjects studied under the courses BBS and BFIA require the understanding of maths topics of class 11 and 12, such as integration, differentiation, set theory, AP and GP, etc. at various stages. So, to avoid any problems in studies that a non-maths student might face, the college keeps the difficulty level of the mathematics section a little high in the entrance test, rather than desisting anybody from taking the test.
But yes, if you have a learning attitude and are ready to put in some extra effort into your preparation, then maths won't be a barrier on the road to SSCBS.
Edit: This answer was written before the University of Delhi had stated its guidelines for the 2015 batch. For the entrance of 2015, maths was a compulsory subject for admission in SSCBS and other colleges offering BMS and BBA(FIA) courses.
