BB Virtuals Prep is an Android application developed by Edu Knowledge Portal, available for free in the Education & Reference category. The app provides a convenient platform for students to access their enrolled test series and related study materials.

With BB Virtuals Prep, users can easily log in using their phone number and OTP, view their enrolled test series, download test papers, upload completed answer sheets for evaluation, and access downloadable PDF study materials like e-books and question banks. It's important to note that the app only allows viewing of enrolled test series and does not support enrollment within the app. Evaluation of uploaded answer sheets is handled by the institute.
