No, you cannot pursue a BDS course after completing an MCA. BDS course is an undergraduate Medical course that requires candidates to have studied Physics, Chemistry, and Biology in their 12th grade and qualify for entrance exams like NEET.
Since MCA is a postgraduate course in computer applications, it does not fulfill the eligibility criteria for BDS admission.
If you are interested in the healthcare field, you may explore alternative options such as health informatics or Hospital Management, which align better with your MCA background.
