Hello aspirant, the basic eligibility criteria to take cat exam is the student should have completed a degree or in a final year of degree. As in under graduation.

Second thing is the student should posses an aggregate of 50 percent in his undergraduation. As in, his percentage b the end of final year or when he decided to take in final year should be 50 a minimum. In terms of cgpa, it should be atleast 5 points.

These are the only eligibility criteria

Hope this helps
