When direct admission will be available in AKGEC though I had cleared UPSEE with rank GN 37672 and SC rank 2545?

You can go through the site of Ajay Kumar Garg Ghaziabad. They will taking admission directly from mid June. You can apply there directly based on your rank in UPSEE and percentage of class 12th. So go through particular website of this College. You will get correct information about it. You can also take part in the Counselling of UPTU.
