What happens when two complete beginners compete to see who can learn more Brazilian Portuguese in 5 days?

Hear me out. Two complete beginners of Brazilian Portuguese get one private lesson a day for 5 days, and on the sixth day, each takes the same OPI (has to answer a list of questions -- and they know what those questions are going in). Whoever does best on the OPI wins that challenge. Say @Tony Marsh and @Fabio Colivier each took a student for 5 days, as a challenge for both teachers and learners. Everyone wins, but also, someone legit wins. Could this be a reality show in the near future? It would definitely be an episode on YouTube. Thoughts?
