The module on datastructures suffers from a few issues: - All the information is at the beginning, with exercises at the end - The module is "hard" for day 1 - The module is often taught at the end of day 1, with concetration waning These issues make the information bit too long and hard to follow. I propose exercises between the different sections. Logical points: - After basic lists and indexing - After slicing, `in`, `len` - After tuples
