The Massive Iceberg Schoolhouse

While you were on YouTube, you found a series by Sweguin called Massive YouTube Iceberg Explained where he explains every entry on the Massive YouTube Iceberg (obviously), and it apparently has 1000+ entries. Not only you absolutely loved the series, you wanted to look at more massive iceberg charts like the one in that series. Eventually, you heard that the iceberg's creator, Potted Plant, is making an internet iceberg with 5000+ entries. So just like any sensible person would, you developed a parasocial relationship with him and constantly DMed him on Discord to see the internet iceberg. A few days later, Potted Plant told you that he just opened a schoolhouse in Thailand where there's not just one, but TEN iceberg charts you can get there, so you immediately booked a ticket to Thailand and travelled to his epic schoolhouse to collect all iceberg charts he made. However, there's a little catch! Potted Plant set it up so you have to answer questions about iceberg charts before retrieving them, and answering incorrectly isn't exactly the best idea in a Thai school. Not only that, he's also brought his whole gang (most of it somehow being entries from his YouTube iceberg) to stop you from collecting all of his icebergs so easily, so you must be careful! You could either get all 10 of the iceberg charts and exit the school, or you could dive deeper into the iceberg schoolhouse and research some of its interesting anomalies...
