Yes, it is possible for a CA student to continue their studies in CA with a B.com at Symbiosis College of Arts and Commerce. They just have to manage their time wisely and give proper attention as well as determination to both of them. The college has no attendance issues. 

However, college can be difficult at times because of comprehension questions, multiple choice questions, written tests, viva, assignments, exams, and activities related to assessments, projects, or lesson plans. The teacher does not care if you're preparing for CA. They would make no negotiations in assignments and any other areas of concern.
