The problem Virtual-Ed solves

Some of the required or necessary features or the features that play a major role in learning might not be present in the app.
In some cases, there are plenty of features in an application including the so-called not so important features or least used features, this of plenty of integrations in one application can be a mess with no proper organization of everything and might make it difficult for users to use, in other words, users don't use the feature which they don't need. Due to this reason, users go with 4 to 5 applications instead of one.
Hence the app can solve all these problems by picking some features which are required by the students as well as teachers.
With a simple UI including all the features.
