i've passed the test this morning. many thanks to this website, it gives me a great help.
take my advice, after studying through the multiple choices, you'd better revise the content once again. It is because all the questions aren't the same as this website.
Actually what i've done is just tried all the multiple choices and read the content of the book once before the test. that is.
any way, thanks again. all the best and good luck for everybodies.
