Unit Description
Midterm:
Extra Karel Practice: It can take some time to learn all of Karel's tricks. Brush up here with some extra Karel practice problems. These reinforce all of the fundamental concepts introduced in Karel, including commands, functions, loops, conditions control structures, and problem decomposition.
Extra Karel Puzzles: A set of all the trickiest Karel puzzles for you to solve
Functions and Parameters Practice: Functions are the critical building block of any program. To be able to use functions, you want to make sure you fully understand parameters, return values, and how to create your own functions. That is what this practice module is for.
