Suresh dani is 1of the well known coaching class in western mumbai for hsc and entrance exams, they have like 6 branches all together I was in the kandivali branch the coaching is quite average not good for an below average student, the chemistry proffessors are quite remarkable also the physics professors.
But coaching lags when it comes to maths, the infrastructure is satisfying, they have regular tests on sundays which is good by a students point of view.
But yes they hav a pretty good record in hsc examinations over the years and its also affordable for common masses in mumbai they aslo have a special private tution for students who are good at paying fees and are looking for better results so all over its was a pretty average but satisfying experience
