Hi social studs!
If you'd like to become familiar with the college board website... go to: http://apcentral.collegeboard.com/apc/public/repository/AP_WorldHistoryCED_Effective_Fall_2011.pdf
This website is great to help you organize your thesis statement. There is a sample thesis towards the end. Read through the document.
If you skim through pages 124-127, you can find example on how the college board wants you to write a perfect thesis statement.
