So looking at the console, you have to do nothing but study for a very long time to reach grade D.
Is the content worth it, doing nothing than clicking the same things for what feels like hours just for one character?
For context at grade E to D:
You study to 17:00 and then study to midnight with a full energy bar, that gives you 15 points.
You can then gain 13 points during the weekend and you loose 5 each night.
But then there is no value to the game as it just becomes a boring clicker, with no content.
If you skip studying at home it becomes near impossible to ever get to grade D as you'll get a max of5 points each week.
