Hi, is the fourth edition math guide is relevant to the 2021 and 2022 SAT? Thank you for answering!
Thank you for asking! It sure is. It was published when there were fewer official practice tests available than there are now, so there are some updated test breakdowns you can get and print out on this site, but otherwise the content is up to date.
You might also consider the online version of the guide, which is up-to-the-minute.
