<p>That's pretty much everything that's been covered on here, add any more you can remember.</p>

<p>“Area of rectangle inside of circle, 4 sqrt 3”</p>

<p>Wasn’t it the area of the rectangle inside a hexagon?</p>

<p>yeah you’re ill fix that</p>

<p>Can you put 4/5 as 8/10 :(?</p>

<p>@js right* but i cant edit it any more<br>
@toby yeah i dont think it matters</p>

<p>… I’m so mad right now!! I’ve gotten an 800 math on my last 4 practice tests, and I got the damn 4092 question wrong??? F***</p>

<p>Yeah I feel really stupid about the (x-y) exponent question.</p>

<p>what about the |ax-1|, how do you do it and was it real or experimental?</p>

<p>for 60 inches 200 years problem,</p>

<p>i think it asked for how many years in an inch, so i fixed it from 3/10 to 3 1/3</p>

<p>I got 3 1/3 as well!!!</p>

<p>Didn’t it say. On a timeline of 200 years the poster was 60 inches, how many inches per year?</p>

<p>^yeah, so think abt it. If each year is 3.3333 inches then 200 years will be well over 60 inches. So 3 1/3 cannot be correct.</p>

<p>Or was it how many years per inch…??? Lol.</p>

<p>It was asking how many inches would represent each year.</p>

<p>I don’t remember so you’re probably right. But I think I wrote 3 1/3… I ran out of time on the last ones… So many careless mistakes = unworthy of life.</p>

<p>I feel ya. I missed the last grid in - the x^y=4096. I took the time to factor and everything…never realized how simple the answer actually was. I, too, am unworthy :(</p>

<p>@ericsnow</p>

<p>i made the same mistakes as you did. I had plenty of time after each math section. atleast 10 minutes but made atleast 1 error on the easiest questions.</p>

<p>it sucks.</p>

<p>:( I thought it was…</p>

<p>60 inches, 200 years how many years per inch so 3 1/3 :(</p>

<p>I failed the challenge of x^y=4096 as well… It was only the first section I have a lot of time to check… The rest… The last question with 800% I did it in like the very last 20seconds… So lucky. And CR and writing I had 5-7 mins to check everything. Perhaps my score will suffice anyway. Do you guys know how long until we get the score?</p>

<p>

I don’t remember this one. Experimental?</p>

<p>@leminscate
i had math experimental and i didnt get that problem. maybe there are two math experimentals.
also, does anyone know how to do the |ax-1| problem?..was that one real or experimental</p>
