How’s everyone else doing on this quiz?
The College Board released a big document today that fills in some of the blanks about the new SAT, which will make its debut in March 2016. I woke up early to dig though it like a little kid on Christmas morning. Rather than trying to jam all my reactions into a single monolithic post, (more…)
So I’m putting the finishing touches on the 3rd edition of my Math Guide. I’ve made a few minor changes and tweaks (a sentence added here, a sentence deleted there) and some more major changes (two brand new chapters). All told, the 3rd edition will be about 25 pages longer than the 2nd edition. I (more…)
All this talk about the new SAT is interesting and all, but we’ve still got two years to live with the old one, so let’s get back to our regularly scheduled PWNing. Here’s a minorly important circle fact that I find a lot of students don’t know: when a wheel is rolling—without slipping—it makes travels (more…)
It’s exciting times around PWN HQ—lots of things going on. 2014 should be a fun year for SAT prep. That has nothing to do with this contest, of course. I just like to open these contest posts with a little friendly chatter. I bet nobody even reads this stuff. :/ ANYWAY, here’s a challenge question! (more…)
I was just noodling around with Geometer’s Sketchpad today, you know—like a totally normal person, and I made this figure, which I thought would make an awesome challenge question. Wasn’t even planning to post a challenge question, and then BAM! Inspiration. In the figure above, equilateral triangle DEF is partially obscured by a semicircle with (more…)
This question was submitted to me the last time I did a question writing contest. It’s pretty good, right? Here’s something I believe to be true: if you can write a convincing SAT math question, right down to realistic wrong answer choices, you’re close to mastering the concepts in the question. That’s because question writing forces (more…)
There are three different kinds of SAT math sections, and it’s important to know which kind you’re working on. Lucky for you, it’s super easy to check without even having to flip through the section. Just look to the top of the first page of the section to see how many questions there are. If the (more…)
Yesterday I went to a museum and waited in line for a very long time for my turn to spend 5 minutes staring at a piece of art that completely mystified me. I guess it’s good art if I’m still thinking about it a day later, even if the thoughts I’m having mostly revolve around (more…)
This morning I was lying in bed waiting for my alarm to go off, and a question just popped into my head. This happens to me fairly often, but usually I’m too lazy to write it down, then I forget it, then I spend the rest of the day trying to convince myself that it (more…)
Just a quick update to let you know that, at long last, the 2nd edition of the Math Guide is available through the Google Play store in all countries I can make it available in.* Now that the 2nd edition is available in this format, I’ve taken the 1st edition out of the store. You (more…)
Note: This post is very specifically about one kind of question. For a broader treatment of function notation, click here. Ah, function notation, that old SAT math bugaboo. I often find that otherwise strong students still struggle with questions that combine graphs and function notation. I’m here to tell you today that, if you’re willing (more…)
