TNEA

There are many best colleges to pursue petroleum engineering such as JCT College of Engineering, Dhaanish Ahmed College of Engineering, Alagappa College of Technology etc.

You won't told me you are in intermediate level calculate in that manner.

Your chances of getting a good college under Anna University are really low with this cut-off score. So, you may try for a decent college in the counselling for BE chemical engineering.

There are few colleges only under Anna University that offer chemical engineering courses in Tamil Nadu. Some of the top ones are Alagappa College of Technology (ACT campus of Anna University), Coimbatore Institute of Technology, VelTech, etc. You may also refer:
