<p>Hi,
Could anybody tell me which chapters i need to konw for the ab test.because it is not clearly indicated in the review which chapters are for AB test only, though it talks about the requirements for AB test, I am just still kinda confused. Since i have only a fews days left till the actual test, I don't want to waste time on the things I don't need to know. So could anybody do me a favour by listing the chapters I need to read.</p>
<p>the numbers of the chapters are just fine!
Really appreciate.Thanks!</p>
