If you fall in general category then the cut off score required for University Departments of Anna University is somewhere near 64 and that of PSG Institute of Management and PSG college of Technology is respectively 35 and 61.

But if you fall in reserved category then for Anna University it ranges from 58 to 40 and for PSG College of Technology it ranges from 56 to 35. But for PSG Institute of Management it's very low i.e. around 30.

Good luck
