hi,

sure you can learn a lot of things from byju;s or any other virtual educational institute.. to crack jee main and advance you need to hard work, and lots of studies.  i think the most fundamental concepts of 10+2 can be clear from schools or any good coaching tution. the main problem of virtual education is that sometimes you cannt get a answer for your problem is immediately. so try to read good study material, make short notes and also follow byjus.. make a strict routine.. so best of luck.

Dear Sukesh, Online learning is a very good option in nowadays check the quality of material that he provides for jee if you feel you learn thing very comfortably than you can say it will help you definitely but you can't only depend on Byjus, you have to put your own extra efforts for clearing or getting good marks in jee. Practice is the key to success.

All the best Sukesh
