SukritiPathak Mess with seniors, especially HOD. Bunk too many classes. Read crappy Indian textbooks. (Edit - I’m not calling Indian textbooks crap, I’m just saying don’t read THAT Indian textbooks that you already know cost no more than toilet paper. Not taking specific names for obvious reasons.) Buy a bone marrow / prepladder / any workout. Get too close to people. Drugs. Alcohol. Virtually any substance abuse. Fall in love. Miss tests.
