Hi Jacky,

JBMIMS takes admission to its management programmes through the scores of MAH CET exam. The admission to the institute is done by Centralised Admission Process (CAP) organised by Directorate of Technical Education (DTE). According to this, the candidates who qualify the exam and meet the cutoff criterion of JBIMS Mumbai get shortlisted for the admission process that includes a writing test, GD and Personal interview. There is no specific preference mentioned for Chartered Accountants in the admission process. You certainly get some points for your work experience in the final selection list though. 

Hope that's helpful. All the best.
