Generally, yes, you should be eligible for MCA in most universities with 80% in BCA Math.

While specific eligibility criteria can vary between universities, the common requirement is a minimum of 60% or 70% aggregate marks in BCA, with a focus on mathematics.

Here's a breakdown of your eligibility:

• BCA Math Score: Your 80% marks in BCA Mathematics are well above the minimum requirement, which is a positive factor.
• 10th Math Score: Although your 10th Math score is slightly lower, it's likely not a major hurdle. Many universities prioritize your performance in BCA, especially in subjects related to the MCA course.

However, it's crucial to check the exact eligibility criteria of the specific university you're interested in. Some institutions might have additional requirements like a minimum aggregate score in BCA, specific subject combinations, or entrance exam scores.

To confirm your eligibility:

1. Visit the university's official website: Look for the MCA program's admission criteria section.
2. Contact the admissions office: If you have any doubts, reach out to the admissions department for clarification.

By following these steps, you can ensure that you meet all the necessary requirements for MCA admission.
