I just took mine yesterday. I did one practice test before to get an understanding of how the test is structured and how long it would take me to formulate ideas and write a coherent essay. What worked well for me was having a game plan going in. I read each position in the 15 prep period and wrote a 1 sentence summary for each. Then I wrote my thesis and planned my supporting paragraphs. This allowed me to spend the whole 35 writing. I recommend doing at least one practice to see what you have time for (some people will be better off writing 4 paragraphs for example). For other preparation I found it helpful to spend the few days before reading a variety of articles and listening to history or current event podcasts so you have some material fresh in mind if you want to use an outside example as support for your argument.

Got this wrong, but makes sense when you see that A is most basic and provable statement. All others make bold claims that are hard to prove with what's in the text. Need to start picking most provable answer for this type of question.

@anonlawapplicant I agree with you, can someone explain why B doesnt strengthen the argument in some way?
