These are copy/paste of the vocabulary from the 20 first levels of the Chinese Learn Online (CLO) course (http://www.chineselearnonline.com/).
Since it's not supposed to replace the online course (paid service), I'm not planning to add any audio file or additional explanations.
I share these vocab lists on Memrise because I believe that the CLO system lacks a great drilling exercise mode.
Moreover, the Memrise platform is much more user-friendly.
