Rate the difficulty of the June SAT

With so few tests of the new format having been administered, it’s still a bit of an open issue whether the released practice materials do a good job simulating the test’s difficulty and content or not. Therefore, if you took the June SAT today, I’d love it if you’d fill out this quick survey. (Curious how the (more…)

March SAT scores and the new concordance tables

Big day today in SAT land—March SAT scores are finally out for most test-takers, and the College Board has released a score conversion app that allows users to compare old SAT scores to new SAT scores. I messed around with the converter a bit tonight. Interestingly, new SAT scores seem to be higher than old (more…)

Official Test Math Explanations

As I did for the last iteration of the SAT, I’ve been collecting the explanations I write on my Q&A sites for Official Test questions in a Google Spreadsheet for easy reference. The new test is still new, so I haven’t been asked MOST of the questions yet, but I figure it’s time to get (more…)

Proving Grounds #2

Here’s the second installment of the Proving Grounds quizzes, which are available for everyone to try for one week before they become exclusive to Math Guide owners.

March SAT difficulty

I never did a post for this survey at the time—just promoted it on social media. However, for posterity, here’s what we learned about the March SAT—the first of the new format—when it happened.

The Math Guide for the new SAT is (finally) available!

At long last, the fourth edition of the Math Guide is available for purchase at Amazon.com, Google Play, and this site (although I’m struggling a bit to keep inventory in stock on this site, so please be patient if you buy directly from me). It will eventually be available at other online locations (e.g., B&N) (more…)

Updates on the new Math Guide: Digital version available now!

The digital version of the 4th edition of the Math Guide is available now from the Google Play store in every country where Google Play sells books. I will have an announcement about the paperback version soon. (One thing that’s not done on the Google Play book is the cover. I’m working with someone to update (more…)
