For a three- or four-year BCA (Hons) degree with a focus on computer studies, several entrance exams emphasize computer science and programming over mathematics. Here are a few options to consider:

1. MCA Entrance Exams: Many universities have their own MCA entrance exams, and they often focus on topics like computer fundamentals, programming, and data structures rather than heavy mathematics. Check specific university syllabi for details.

2. GATE (Graduate Aptitude Test in Engineering): While GATE does cover mathematics, some sections focus heavily on computer science topics. If you choose the Computer Science and Information Technology (CS) paper, you can delve into programming, algorithms, and database management more than advanced mathematics.

3. IBM or Cisco Certifications often have assessments that focus on practical knowledge and skills rather than theoretical mathematics.

4. University-Specific Entrance Exams: Some universities might have their entrance exams for postgraduate programs that focus on computer science topics—research-specific programs for detailed syllabi.

5. Data Science and AI Programs: Many entrance exams will emphasize programming and data handling rather than pure mathematics if you’re looking for specialized programs in data science or artificial intelligence.

It’s essential to check the specific syllabi of the exams you’re interested in, as they can vary significantly from one institution to another.

Hope this helps. Good luck!
