MAT

Hello Sahana,
You should go for any entrance exam because without any entrance exam, you will not be able to get a good college and there may be a possibility that you get a scholarship if the college offers the scholarship and you fit in their criteria. You can go for May MAT 2018.

Hi, Without GD, you will not be able to get admission. Therefore, I would suggest you to contact the colleges in which GDs are still going on.
