Hello ramya,

You have a relatively low percentile to get admission in GCT college, but you can get admission in other colleges,

I'm providing you list of some colleges -

1. Thiagarajar School of Management,Madurai.
2. Sri Sivasubramaniya Nadar College of Engineering, Kancheepuram.
3. PSG College of Technology,Coimbatore.
4. St. Joseph’s College of Engineering,OMR,Chennai.

you can try in these colleges,as your admission chances in these colleges are more.

I hope it helps,

Best of luck.
