Which is the best distance learning program for jee main and advance?

Correspondence course by resonance or fiitjee

For the correspondence courses provided by some of the coaching institutes you can refer to:
Resonance: If you want nice notes along with formulas, a lot of practice problems and you are not so well in theory, then go for it for both JEE Mains and JEE Advanced.

FIITJEE: If you really want to test your knowledge, skills and aiming to take very tough challenging problems or aiming for a top rank, go for it.
Some other are:
Vibrant Academy
Vidya Mandir Classes

Good luck.
