Sometime between 730 and 740, after the Tang restoration, a section requiring the composition of original poetry (including both "shi" and "fu") was added to the tests, with rather specific set requirements: this was for the "jinshi" degree, as well as certain other tests. The less-esteemed examinations tested for skills such as mathematics, law, and calligraphy. The success rate on these tests of knowledge on the classics was between 10 and 20 percent, but for the thousand or more candidates going for a "jinshi" degree each year in which it was offered, the success rate for the examinees was only between 1 and 2 percent: a total of 6504 "jinshi" were created during course of the Tang dynasty (an average of only about 23 "jinshi" awarded per year).
