复合句中的从句分析

The chemistry exam was postponed which was exactly what we wanted.

在定语从句后又来个从句，这个属于什么从句？怎么理解它的结构呢？

The chemistry exam was postponed, which was exactly what we wanted.

which的先行词为主句内容时，这个定语从句一定是非限制性定语从句，需要用逗号和主句分开。

which在从句中作主语，was为系词，what we wanted为名词性关系分句作表语。即定语从句为主系表结构。what=the thing which。
