你可以看下handbook，概率，数理统计，线性代数都是需要的。个人以为，只要读过大学的数学，应该都可以的

Good!.....maybe not very difficult!!

for the handbook reading, higher education mathmetic is required, but for the exam, not very difficult,  any candicators ,who passed university math course,  will pass exam II easily.

大学的数3水平就行吗？

看楼上几位的解释，数4应该也是够的
