Yes, you are eligible for JEE Main 2025 even with 55 marks in Mathematics in Class 12.

The minimum eligibility criteria for JEE Main generally require candidates to have passed Class 12 or its equivalent with Physics, Chemistry, and Mathematics as subjects. There is no specific minimum percentage or cutoff required in any of these subjects.

However, it's important to note that while you may be eligible, securing a good rank in JEE Main will require significant preparation and focus on all three subjects, including Mathematics. A low score in Mathematics might make it more challenging to compete with other candidates who have higher scores in all subjects.

If you are determined to pursue engineering and have a strong interest in Mathematics, it's recommended to:

• Strengthen your Mathematics skills: Dedicate more time to practicing Mathematics problems and concepts. Consider seeking additional tutoring or online resources to improve your understanding.
• Focus on JEE Main syllabus: Align your preparation with the JEE Main syllabus and prioritize topics that are frequently tested.
• Practice regularly: Consistent practice is key to success in JEE Main. Solve as many mock tests and previous year question papers as possible.

By following these steps and working hard, you can increase your chances of securing a good rank in JEE Main and achieving your goal of pursuing engineering.
