In my opinion ,VM (vidyamandir tutorials)is the great place to master your concepts ,if you know how to take advantage.
There are regular sessions for every subjects ,with different teacher's guidance for different subjects. My child have improved her knowledge and have cleared the conceptual doubts with the help of experts .The revision programmes and the regular test on all subjects have been a greater deal for my child scoring good marks.
There is a regular checking of the students practicing their Maths sums,topography,some grammar excercises and other practical work. Presentation of the answer sheet is a greater considerable fact for the teachers over here, thereby improving the over all academic performance of students.
Ones hardwork and study help from VM would definately strive one to score good marks !
