<p>I just got back from my SAT and I had two grid-in math sections one right after another. One was REALLY hard. I remember one question about a schools number of students (there was a chart) and the last grid-in was about some carpet company. Hopefully this section didn't count.</p>
<p>Yeah, I had the same thing on my test...I thought the first of the two math grid-ins was harder</p>
<p>do you remember a question?</p>
<p>there was a question that said that some code for something consisted of a letter (excluding O) followed by two numbers (1-9 inclusive); how many different combinations are possible? I thought I put 25, but that would make absolutely no sense</p>
<p>the three character code was NOT experimental. my test had verbal experiment, but I had that questions.
it was a "counting principle" question. three characters to designate radio station license.</p>
<p>Wow, they have two grid-ins for an SAT? I didn't know that. This will be my second SAT testing, and I've never had two grid ins. That must suck.</p>
<p>So the latter math section was the real one?! NO!!</p>
<p>2 coordinates with (a,b) and (c,d) are on a coordinate plane.
A^2 + B^2 + C^2 + D^2 = 268 (I think)
ac + bd = 81</p>
<p>What is the distance? How do u do this one?</p>
<p>just to clarify, you didn't have one with a graph that talked about student absences did you?</p>
<p>ugggh was that a real one? :[ Was that the one that had the question about "which traiangles are always similar" and had the funky graph with the range and asked how many times the transformation graph hit x axis?</p>

Isn't that the distance formula?
sqrt((d-b)^2 + (c-a)^2) is the distance.
2(ac + bd) = 162
and so on.</p>
<p>i think that problem was an experimental anyways and the answer to the alphabet except O and 0-9 inclusive was 2500</p>
<p>Just to confirm, what was the answer to "which triangles are always similar?"</p>
<p>that was only equilateral triangles :]</p>
<p>That's what I put too, good.</p>
<p>Does anyone remember that really hard math section and specifically that question about student attendance/a LAST gridin about a carpet company? </p>
<p>That is the only real way i'm going to be able to figure out if that section was counted or not.</p>
<p>was the triangles one, the second math section or the first one?</p>
<p>I only had one math grid in and it was the permutations one with 25x10x10=2500. I think the last question was find the slope between A and B and A was (3,4) and B was (1,2) or (2,1).<br>
There was also another one with "which 2-digit number has three factors." THat one took me a long long time to figure out.
Collegeboard's calendar says that Nov scores will be online on the 20th, but on the "My SAT" page it says it will be available the 22nd. Two extra days is a long time to wait.</p>
<p>"The 2-digit number that has three factors" problem took me literally two seconds, right after I read it the number 49 miraculously popped up into my head, it was kind of creepy, I was telling my dad about it, I sort of felt like John Nash. The first two math sections were so easy that I had ten minutes left over after each of the sections, but the last math section was a bit harder, only due to the last two problems, but overall it was all pretty easy. I am pretty sure I only got one problem incorrect.</p>
<p>But I still can't figure out what my CR experimental was!</p>
<p>do you remember if there was a grid-in about carpets or a problem that required you to look at a graph to find out the total number of kids at a school?</p>
<p>I don't believe I had that, though my memory is pretty shot. But I would bet that was your experimental if you had four math sections.</p>
