IF U join in any other government school it is better because GOVERNMENT SCHOOL>NARAYANA E-TECHNO/OLYMPIAD/CO branch the teachers collect fine for us for speaking in regional language but they speak telugu always then who wll collect fine for them they take fine and eat it. they never try to correct the students.last year for graduation day for class 10 they told us to bring money for it and for that when management will give some money they will not share the happiness but gobbel it up.teachers teach to mug up iit books and they never touch cbse text books but give question paper before the exams, which is illegal.they give preferences only to telugu people.I being a non-telugite have not done homework once but they called my parents and complained whereas a telugu student will not do the homework daily but they dont punish him.higher officials of narayana institution have a very bad attitude,before joining they act like angels but afterwards they act like devils they torture the students and teachers by scolding them in bad words,they dont have proper communication skills they only speak telugu and communication between teachers is telugu,even telugu medium schools are better...if u dont score good marks in iit they dont correct you but start using abusive language and beat the students.so if u want your child future to be bright dont join him in narayana e-techno school/olympiad/co schools
