REAL LIFE EXAMPLE:
my school gives an app for students and another app for teachers and my teacher ask me to submit an assignment if i send that assignment to my teacher and my teacher evaluates it and if the assignment is good and up to the mark in the teacher's app the teacher should enter the student's name and there will be a button called give coins so if they pressed it 10 coins will be added in coins section in student's app..

ITS A BIT DIFFICULT I DON'T KNOW HOW TO MAKE IT PLEASE HELP ME..

This could be done using a Google Sheet, with these columns:

  • Teacher Name
  • Assignment Details
  • Student Name
  • Submission datetime
  • Submission URL of video on YouTube or Loom
  • Judging datetime
  • Payment given

See FAQ Section: Google Sheets
