Questions tagged [gridworld]

The GridWorld case study provides a graphical environment in which students can experiment with different types of objects and observe how programming changes will affect the behavior of those objects. It is a required part of the AP Computer Science curriculum. (Computer Science A students are expected to be familiar with the material in Parts 1-4 of the case study narrative, while AB (discontinued) students are required to be familiar with all 5 parts.)
