Hello,

Yes, you can appear in IIT JAM with 65% in 12th because you don't need 12th marks in IIT JAM. In IIT JAM they need your bachelor's degree, and you must have a minimum aggregate mark of 55% in this degree; then you can appear in IIT JAM. This means overall IIT JAM doesn't need 12th marks; instead, it needs bachelor's degree marks.

I hope it resolves your query!!

Yes, the IIT JAM Mathematics syllabus is mostly the same as what is taught in B.Sc. Mathematics. Core topics like Calculus, Algebra, Differential Equations, and Real Analysis overlap. However, JAM tests deeper understanding and problem-solving skills, often at a higher difficulty level than typical B.Sc. exams. Some topics may also be covered more rigorously or appear in more applied forms. So while the syllabus is similar, focused preparation is needed to match JAM’s level.

Hello

With an IIT JAM rank of 2167 in the General category, top-tier Indian Institutes of Technology such as IIT Delhi, IIT Bombay, IIT Kanpur, and IIT Banaras Hindu University are unlikely options, as their closing ranks are typically in the low hundreds to a few thousands. However, you are still in a good position for several reputable government colleges through both the IIT JAM counselling and the Centralised Counselling for Master of Science and Technology (CCMN) channels.

If you belong to the Scheduled Caste category, you have a strong chance at getting admission to IIT Banaras Hindu University in the Master of Science in Physics program.

If you are in the General category, apply through the Centralised Counselling for Master of Science and Technology to National Institutes of Technology such as NIT Silchar, NIT Srinagar, and others.

You should register for the Centralised Counselling for Master of Science and Technology for admission to National Institutes of Technology and Centrally Funded Technical Institutions, and carefully prioritize your preferences in subjects like Physics, Chemistry, or Mathematics.

You may also explore the Indian Institutes of Science Education and Research option:

If you are interested, register for the IISER Aptitude Test and aim for a rank below approximately 2000.

Keep alternative plans in mind:

Consider reputable National Institutes of Technology in your state or nearby, such as the National Institute of Technology Agartala, National Institute of Technology Nagpur, and similar institutions
