Lesson 3 - Pieces' Value, Attack and Threat: Exercises
Even though exercises are not required, I recommend working on them. They will help you grasp and practice the things you learn from the lessons more efficiently. You can certainly go back and sneak in the previous pages... but try first to answer the questions without going back. By doing so, you will make your memory work a bit and it is a pretty good thing to keep the memory working if you want to become a good chess player.
When you are done, you can use the Verify button to see you results. If you want to do the exercises all over again, use the button Do it again.
