GPT-4 is so close to creating a universal educational simulator based on just a paragraph prompt. Take a look at this simulated negotiation, with grading and feedback. Prompt: "I want to do deliberate practice about how to conduct negotiations. You will be my negotiation teacher. You will simulate a detailed scenario in which I have to engage in a negotiation. You will fill the role of one party, I will fill the role of the other. You will ask for my response to in each step of the scenario and wait until you receive it. After getting my response, you will give me details of what the other party does and says. You will grade my response and give me detailed feedback about what to do better using the science of negotiation. You will give me a harder scenario if I do well, and an easier one if I fail." I did this with GPT-3.5 a month ago and it was nowhere near as good (GPT-4 also seems more willing to give worse grades than GPT-3.5 - which is good)
