Hello shivani...

In PSG TECH, merit admission is possible only through TNEA Counselling (State Board). For Non State Board students, like CBSE, IB, etc, admission is possibly only through management. Management is also possible for State Board students who don't get admission through counselling .

For Admission through management, they have a Base mark for all boards like 170+ cut off for State board, or 70%+ for CBSE.( Not sure of the exact base mark). If you score above the base mark, you are eligible for Admission.The price for a seat remains the same even if you have got 90% or 71%.

Last year, the price for CSE was 15Lakhs and ECE was around 15-20 lakhs. Prices for IT/Auto was 12 lakhs. Mech it is 20Lakhs+ And I heard the price was increased this year. Not sure tho.

Best of luck...
