Hye Shanmathi,

Most of the colleges are given out their application forms by now. And they will accept MAT score of Sept 2017 also. A MAT score is valid upto one year from the examination date. That means you can apply to colleges with that MAT score upto September 2018. Now then, most of the colleges have openings now, but they will be closed by March or April depending upon the college. So, I suggest you better start filling out forms as soon as possible, because they may be filled out if its too late.
