<p>Well, i didn't see one anywhere so here it is. I'm pretty much solo on this exam, even though i take the AP course idk how my teacher even got a degree in education anyway i'm using the Barrons book on this, is this is a good book- meaning is it too hard or just right. I'm not doing so hot on the chapter quizzes.</p>
<p>i tried barrons. it’s hard to get through the info.</p>
<p>i switched to using princeton yesterday. it’s going much faster, but there aren’t many practice problems. </p>
<p>i think i will do the barrons problems after reading princeton. their questions are pretty tricky to me- like there are little twists.</p>
<p>my teacher teaches acc. to him “above the ap level”, but we started reviewing about a week ago. before then, we had never seen an ap FR, and we have yet to have an official practice ap MC.</p>
<p>i’m so not ready! argh :(</p>
<p>Haven’t used any practice books at all.
Our teacher has been giving us enough practice already…three full-length practice tests so far lol (both FR + MC). Scored a high 4 on the first one and low 5’s on the other two.</p>
<p>One thing I’d recommend is to REALLY review all the old stuff (regression, LSRL, residual plots, exponential to power transformations and vice-versa, adding/subtracting means and variances for LSRLs and the binomial/geometric probability rules). You kind of have all the Inferential Stat stuff in your head because you recently did it, but reviewing these old concepts which are really easily forgotten can help a ton.</p>
<p>I swear to god, barrons for AP Stat is one of the worst i’ve seen. I discovered it a bit too late, i need to find some other review online, does anybody have a link that is reputable.</p>
<p>A quick stat-related question…say you have a preference poll between orange juice and fruit punch. Say it’s .8 oj, .1 fruit punch, and .1 undecided proportions in a sample. If you’re interested in the difference between the proportions in oj and fruit punch, could you do a one proportion z-interval with .7? Why or why not? Also, does the undecided play any role in this? Finally, what would you need to do to use a 2 prop z-interval for the same difference?</p>
<p>oh crap…i have barrons…i didn’t think it was bad or anything…but now i’m worried…is it not like the real test??</p>
