Help me to prepare for the writing test, please :)

I am planning to continue my study at the US. Therefore, I need to prepare myself for the GRE test. One of the sections of the test is Analytical Writing Section. On that section, there are two tasks, the first is to present the test-taker perspective on an issue, and the second is to analyze an argument.

Now, I would ask for your favor to overview my writing on every posts of this blog, so I can improve my English writing :)

Thanks in advance ;)
