There are some very basic tips one needs to follow that might prove to be really helpful for a student of Anna University. Some of them are:
Make sure your handwriting is neat and beautiful. Surprisingly enough how you write matters more than what you write.
Use bookish language more than your own words
Interactions with the opposite gender might put you into serious trouble
Don’t oppose the professors no matter what they say. Respect them.
Do not use left hand for offering anything
Moustaches are necessary if you are a man and flowers+gold jewelry if you are a woman.
I know all these points are a bit weird but it’s true. Tamils respect their culture a lot and you might get disciplined for inflicting damages to it.
