好紧急啊，我复习GMAT已经2年了，我的目标是700分，但是上次的考试我得到了680分，主要问题我判断是出在remainder和even&odd的问题上。在近期的复习中，这类型的题还是让我屡屡受挫。还有10多天就要进行下次考试了。希望各位高人能够加以指点，如何能够解决这类型的题，解题思路或者题型总结。remainder和even&odd的例题如下：

I know this DS remainder format question:

Q1: When x is divided by 6, Do we know the remainder？(ans: D)

Q2: When x is divided by 4, Do we know the remainder？(ans: A)

Q3: When x is divided by 9, Do we know the remainder？(ans: B)

Q4: When x is divided by 36, Do we know the remainder？(ans: C)

(1) When x is divided by 12, the remainder is 5.

(2) When x is divided by 18, the remainder is 11.

What about this DS remainder format?

Q5: Does m, which is an positive integer, divide evenly into 6?

Q6: Does m, which is an positive integer, divide evenly into 4?

Q7: Does m, which is an positive integer, divide evenly into 9?

Q8: Does m, which is an positive integer, divide evenly into 36?

(1) m divides evenly into 12.

(2) m divides evenly into 18.

(any other remainder question format is helpful!)

在此先多谢各位！！
