Dear students, As everyone is saying "start from basics".What is basics?. Learning new concepts from experts in subjects is the normal procedure .Very important is learning from experienced teachers who are experienced to hear the students. Expertise is important but hearing the student achieved through patience,experience and contentment counts the most Sense the issues of individual students and try to solve their problems, solving their subject problems are secondary. Teaching a mass of student with a mass of expert teachers is one method of teaching; it has some advantage also But Sai's classes have a different way! My students are still keeping a good relation even after reaching prestigious position declares that The bond between teacher and student is not bound within the classroom or till the class time It lasts for a life time.This is the basics Sai's class is believing. Regards Sai Sundar S Sai's Classes
