Hi. I applied to Christ with my Sep MAT score of 635 marks but in Dec MAT i secured 685 marks. Should i reapply or leave it as such?

Hi. Here, your MAT score just shows that you are eligible to apply to the institute. Any score above 600 will do. Reapplying would just delay the process of admission. It will be better if you just go ahead with the Sept score.

You need not apply again. Marks are just an eligibility criteria for selection to admission process. Later you will be assessed on your performance in MP, GD and PI. You can put forward your Dec marks too, if you want, in your resume once you are selected for PI. All the best!
