* * * There are two versions, the latest version was released in 2008. I have seen both versions. Personally, I don't think the difference is very big, but the pricing behind it has gone up again after the revision!
There is absolutely no need to look at the advanced number when you have to cope with the graded exam after entering the freshman year. The content of the exam is completely within the scope of the college entrance examination. The school just wants to know the real level of students through this exam and prepare for the next teaching! So it's best to show your true self, which is good for everyone!
