Hello Aarthy,

You must be using the free application, once it ends you need to purchase a premium package of Byju's. The course that is available is not the full course until you purchase a package.

The free application is missing many features like knowledge graph, Access to byjus portal and mentor support.

It also cannot get the benefit of question papers and solution papers in the free application.

I suggest you to purchase it if it is helping you. You can contact the Byju's helpline and arrange a session where the salesperson comes to your house and explains you the packages and their benefits which will help you understand the Byju's portal better.

Hope this helps.
