Chemical Engineering

Hi Maya, if you get chance to study abroad then never lost this chance. The four branches are different and your question has a very individual perspective. Everybody will have different opinions. As for me, I enjoyed electrical and electronics. Similarly, you will have different interests, so there cannot be any generalized answer to your question. There is no the toughest field in engineering if you have more knowledge or study hard hope you understand and good luck.

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:
