kya is app mai pement karna padega ya free hai

Both.. if you want to use this app free of cost then no problem use it.. but if you need some other facilities then you'll have to pay for it.. (I mean get premium)

Jaisa Aap chahoge free me Bhi bahut se lession hai jisse Aap asani se English seekh sakte hai Agr teacher se Sikhna chahoge to paisa lagega.
