Thanks for reading Ogun! It's possible to submit as autograding.json, although I haven't tried that yet. In fact, you can peek what classroom does automatically after student forks the repo to start its coding. Example: https://github.com/igormcoelho-learning/practice-autograding-cpp-igormcoelho/commit/588674d7e9c689b73500848d472475a7584bed20

There's also some community for github classroom professors, so it's nice to join there and interact a little bit :)
