problem related to reaciving certificates

Hi Jatin,

Khan Academy is not an accredited school and the work done on the site does not count towards a diploma. Khan Academy is best used as a supplement to your normal schooling, whether that is homeschooling, or a traditional school.  Good luck!

For the most part, I agree with the other comment (not an accredited school).  However, I haven't had a problem using Khan Academy as the main math curriculum for homeschool students, supplemented with https://www.thatquiz.org/ for rote memorization drills.
