Are there any other websites that have step by step Gridworld Free Response Questions?

I am still having a lot of trouble trying to do a practice AP exam with Gridworld.

Free Response Questions About GridWorld

  • One of the four free response questions will be about GridWorld
  • The GridWorld question is worth the same amount as each of the non-GridWorld questions, so don’t spend excessive time on it
  • The act() method is very important
  • Don’t modify the act() method in Bug or Critter nor override the act() method in a subclass of Bug or Critter
  • Use the Quick Reference Guide to confirm your answers but study GridWorld in advance of the exam so you don’t have to spend a lot of exam time looking up information
