i don't have knowledge on the kbs college fees for bcom, but i would love to give big shoutout to IIM SKILLS investment banking course, for those with financial sector interest. because my cousin finished it and secured a job in top finance firm with 4.2LPA
Typically, for direct admission, you will be required to take a lateral Entry exam specific to your course. However, some colleges give direct admission basis 1st year marks as well. What you should do is visit KBS college, go to the Admissions Office and find out directly about the process. There is no information available online on their official website regarding this matter.
Sorry to hear about your loss. Please visit the Keshavji Bharmal Sumaria Commerce & NATARAJ Professional Sciences College campus to understand the facilities provided by them for such situations.
