Also she's the first female teacher from whom i've studied 11,12th chapters as mostly the teachers for +2 science are males but like- im pleasantly happy, Subscribed!

Further, the teaching profession on youtube is generally male dominant (Expt-zoo and bot subjects) So In that case, if I happen to find some good non male teacher like her why would you find fault with my making comment on that...? I know this is quite controversial and a debating topic and that I'll have to be ready with my sleeves up as tons of criticism for my comment in near future, seems no far...
