Dear Student ,

The eligibility criteria for appearing in IIT JAM for admission in M.Sc Maths is as follows :

• Should pass in  class 12th
• in Graduation , Mathematics should be there for at least 2 years or 4 semesters .

As per your details , you have studied Maths in only three semesters , so you're not eligible to appear for IIT JAM.
