This time I feel the math part is relative tough since many problems just like RCs.. However, the JJ part in my test is realy true. So XDJM: Please do't waste too many time to recheck again, just drop the answer and save more time on other tough reading math questions...

I am so upset that both math and Verb are terible, even I feel the questions during the test. are not very hard to read. I have no idea. If you have good suggestions, please kindly help me. My Toefl is 550.

My advice is that, E.T.S tend to tougher the math reading, and verbal questions as well, so don't waste too much time if certain question you cannot give answer within 2 fenZhong!!! You will find no tiime to do all other parts...

Don't pay too much on CR/SC JJs and RCjjs as well. It will not help, only to get familar that's enough. Hope you will agree with me soon!

Thanks GR and I think you did a good job and I would like to serve BanZhu, if possible.

Additional RC

1. Global warming.
2. South African women movement (old jj-african american women 's movement.
3.4 Forget now, sorry
