 :- Rating article as ""B-class"" according to the following standard: 
 :- Useful to many, but not all, readers. A casual reader flipping through articles would feel that they generally understood the topic, but a serious student or researcher trying to use the material would have trouble doing so, or would risk error in derivative work.  
 :-Considerable editing is still needed, including filling in some important gaps or correcting significant policy errors. Articles for which cleanup is needed will typically have this designation to start with."
