ganga pun sir was great, even though i didn't take any classes with him he looked like a dude with some dicipline, i heard senior saying that he was kind of strict. and purna nepai " HAMI JHALMAL, HAMI JHALMAL, BIRENDRA SAINIK MABI JHALMAL HAMI SABAI JHALMAL" he was always like he was the best in his field and nobody could beat him. so he was so so. I hated basuki regmi. pawan malik, mathema(math) and others were ok.
