I need to make a study guide and have no idea where to start. Here's the prompt:

Your task is to create a Review Tool which covers the material we have covered in Period II so far.
This will include Chapters 3 and Chapter 4. Plan to have 1/3 of your Review Tool cover Chapter 3 and approximately 1/3 cover Chapter 4 and the remaining 1/3 cover the combination of the two chapters. Do not use more than two sides of one sheet of paper.
Your Review Tool should include a vocabulary section and a portion which integrates the Empires of Chapter 3 with the Religions of Chapter 4.
