CA

Dear aspirant, Great interacting with you. Yes it's definitely possible to do CA and BBA simultaneously. Indeed many students do both the things together and crack both the courses with good marks. However, both BBA and Chartered accountancy are courses which require proper study and time for understanding the subjects. But it may too difficult for you to handle both of them together. It all depends on your capability of studying. If u think you are intelligent and smart enough to mange both of them together. U can go forward. But if u think u are a bit weak to manage both of them together then you may wait till your BBA gets over. Hope it helps. If you found it useful then upvote or thumbs up my answer. Good luck.

Dear aspirant, Great interacting with you. Definitely you can study Chartered Accountancy Course after completion of BBA. The minimum qualification required for admission in Chartered Accountancy course is 10+2. The CA course comprises of CPT, IPCC, Articled Training and Final Course. You can also do CA and BBA simultaneously. Indeed many students do both the things together and crack both the courses with good marks. However, both BBA and Chartered accountancy are courses which require proper study and time for understanding the subjects. CA is definitely one of the best things, even after graduation. But be sure that pursuing CA is of much less value; only if you clear CA then it becomes much worthy. Hope it helps. If you found it useful then upvote or thumbs up my answer. Good luck.

Doing both at the same time is manageable to some extent but prioritizing both of them is quite difficult. I would suggest that if you are planning to do any professional course like CA CS CMA or any other, it would be best if you pursue your graduation from distance learning. If you take regular college it would get really difficult for you to manage both of them (saying that because of my personal experience)
Also, there are times when some exam dates of CA & B.Com from DU clash with each other, like one of my friends is doing CA with B.Com (regular college) and one of her exams on 25th May got clashed, so she missed B.Com exam (I don't know how and when will she be able to give that again) but she gave preference to CA that means she's clear with her priorities, so it's very much important before doing any course to know your priorities and work accordingly. Coming to the syllabus, honestly, you won't find much difficulty in doing and completing the B.Com syllabus while pursuing CA since most of it gets covered in CA. To conclude I would say go for it, cover both the courses, know your priorities and choose wisely from where will you do B.Com. All the best!
