There are no reservation criteria for the Common Management Admission Test. However, Common Management Admission Test participating institutes have to abide by reservation criteria for educational institutions set by the GoI (Government of India) during the admission process. Students planning to pursue a Master of Business Administration can check the reservation criteria for the particular college at its official website of the Common Admission Test and fill out the application form accordingly. For more information, you may visit the Shiksha CMAT exam page. (https://www.shiksha.com/mba/cmat-exam). I hope this will help you.
