The usage of ChatGPT in this chat involved language translation and communication assistance. The key prompts were:

1. The initial request to translate a message to Spanish, specifying the context of dropping off a car for painting (Beginner level).
2. The clarification that the car doesn't have to be painted immediately, but to drop it off for painting on Monday (Beginner level).
3. Asking if it's the same location and if 4:30 PM is okay for dropping off the car (Intermediate level).
4. Adding a greeting and explaining the situation with out-of-town travel and using the sister's van (Intermediate level).
5. Inquiring about the payment schedule upon pickup (Intermediate level).
6. Sending a follow-up message asking about the progress of the paint job (Intermediate level).

Overall, the user's prompting suggests an intermediate level of proficiency, as they were able to ask for specific details and engage in a conversation with appropriate context.

Me: Ashamed to say it but my Spanish is horrible so this grade makes total sense
