Hey Abhishek,
You can do it by calling a microflow on the approve and reject button,
In the microflow, just apply a change activity which changes the status of the application to approved or rejected respectively,
something like,
Appname.Enum_status.Active
you can refer to the image below,
You can follow the link to know more, (follow from step 3)

Hope it helps!

Hi Abhishek,
By setting default value you active waiting for approval while creating request, and give only read access to the student
in approve or reject flow you can change the status by change object activity.
