Attempt the following. Spend no more than 20 minutes on a challenge activity or lab (unless you want to).

• complete at least 80% of the Participation Activities in each section 6.11–6.18 of the zyBook
• complete the following Challenge Activities/zyLabs—for every challenge activity you cannot pass at least one test for, please take a screen shot of your final attempt after 20 minutes and submit that here (make sure your photo includes the challenge number)
