The BYJU'S App was the first place I would go to, whenever I had any doubts in any concept. It was an integral part of my JEE preparation. The daily practice problems helped me revise and strengthen my concepts along with increasing my speed and accuracy.

Kunal Kundwani | AIR 63 - JEE Advanced 2020 |

The videos on the BYJU'S App aided in improving my weak areas in Chemistry. It was helpful in my preparation and I got to learn concepts in a different way. Practicing the mock tests and the AITS, along with the extensive analysis helped me identify my weak and strong areas.
