Ah, the engineer who thinks everything can be solved with software.
To automate grading you first must create a general AI, because if you just do multiple choice exams, you aren't really testing or measuring someone's ability to perform the task, you're just measuring their ability to make a good guess. And some teachers do that. But not the good ones.
As for planning, some senior teachers have filing cabinets labeled by day. They just reach into the file and pull out the lesson for "day 82". But any good teacher will realize that they have to customize the learning to that year's kids, and constantly update with new teaching methodologies, new information, etc. And sometimes the school adopts a whole new curriculum, and then you have to start all over.
