I need an Android app. I would like it designed and built it
1. We (admin) should be able to upload pdf/word files, videos, images and data (data or theory may contain scientific/mathematical symbols).
2. User should be able to comment on videos/images/data.
3. Different types of tests that should be available in the app –
i) Objective (Single correct/Multiple correct)
ii) Fill in the blanks (Alphanumeric)
iii) Match the pair (Single correct/Multiple correct)
4. Admin should be able to upload new tests.
5. Test analysis/ result should be generated automatically.
6. Payment for various products as and when required while navigating inside the app.
Please go through above points and revert back with the expected timeline to complete the project and cost estimation.
