The information might be somewhat outdated since there are at least 31 activities on Grandomastery currently, which is pretty impressive. It's amazing how many things can change and how a project can be enriched so drastically in just a year. When there are only 15 minutes left in a class, my teenagers and adult students know that it's Grandomastery time. Just a quick suggestion - if their resource teachers read this, maybe they can include activities centered around particular topics, such as design, healthcare, and travel. ESP students could benefit from more activities designed for business English learners. All in all, grandomastery is a great idea!
