#### Extensive Experimental Concepts

All our courses include a lot of experimental ideas to make students understand the topics very easily. We use our day to day life objects to draw parallels to the concepts and make students learn from our surrounding. Our science courses use a lot of experiments for the students to make the visualizations stronger for the ideas as visual memory helps them retain the concept for a more extended period. We innovatively bring our courses closer to the real-life so students can learn better with their daily objects.

## What our students and parents say about us!

I would like to thank Edusaksham on behalf of my son Aditya who attended " Math Olympiad crash course for 5 weeks". As per Aditya, this course helped him to understand new topics like Roman numerals and decimal places which were not taught in his school till date and had a better understanding of other topics. I personally thank EduSaksham for all the help and support.

### Deepak Sharma

I have grown up in a family where my father used to give me practice maths paper every day which I need to finish before I go to play. I think that strong foundation of solving new questions every day helped me to clear my IITJEE exam. But as working women, I always had time challenge to create practice Math papers for my daughter. Thanks to EduSaksham, their questions are so logical and conceptual that I don't feel the guilt of not creating practice questions by myself :). There are plenty of worksheet along with the tutorials for each chapter. It has made parents life easier :) And the best part is my daughter loves doing it. Thank you EduSaksham.
