* NIMCET (National Institute of Technology MCA Common Entrance Test): While NIMCET doesn't explicitly *require* math at the 10+2 level, strong math skills are highly recommended because the exam itself contains a substantial mathematics section. A weak background in mathematics will put you at a considerable disadvantage.
* UPSEE (Uttar Pradesh State Entrance Examination): Check the specific syllabus for the MCA section. Some years may have emphasized math more than others.
* Other state-level and university-specific exams: Many universities have their own MCA entrance exams. Their requirements vary wildly, some requiring a math background at 10+2, others not. You MUST check the eligibility criteria for *each specific exam* you wish to apply for. Their websites will have the most up-to-date and precise information.
In short: The fact that you only have Mathematics at the 10+2 level might limit your options. To find suitable All India entrance exams, you *must* consult the official websites of each exam and university you're interested in. Don't rely on generalized information; check the eligibility criteria meticulously. If math is a weak area, consider focusing on exams where it's less heavily weighted, but be prepared to work exceptionally hard to compensate for any deficiencies.
