Programming Diagnostic
Check Python semantics, data-structure selection, algorithmic control flow, and recursion.
Programming
Control Flow Practice
Build reliable branching, iteration, function, comprehension, and trace fluency.
Data Structures Practice
Select and use lists, mappings, sets, stacks, queues, heaps, and graph traversals.
Python Practice
Eliminate mistakes in slicing, sorting, mutability, aliasing, iteration, and complexity.
Recursion Practice
Practice base cases, call traces, and recursive decomposition.
