@scott,

Change your display preferences to "show pinyin" in your account settings (under "Extra Stuff") and the pinyin will be displayed below the characters on the multiple choice test questions:

You can also restrict the question types to not include generative questions (where you won't get the pinyin hints) here:

Best,
