Hi 华金,

Thanks for the support! First things first, you can change your spaced repetition settings on the following page:

http://popupchinese.com/account/review

That said, if you just want to practice reviewing from your vocabulary list, go to your vocabulary list (http://popupchinese.com/vocabulary), select the words you want to review and then click on the "review" button in the left-hand sidebar. You can also change your default page length to make it easier to select *everything* if you want.

Alternately, if you are viewing a set of labelled vocabulary and click the review button, it will prompt you to review the entries in that set without the need for manually specifying which words you want to review.
