This page is an index to the math questions that have appeared on SATs
released via the College Board QAS or as Official Practice Tests. The
questions are arranged by topic, and each is described briefly. The number
of faces shows the difficulty level. Questions in red appear as part of the
first three tests in the second edition of the College Board Official SAT
Study Guide. Click the links below to jump to the desired topic. This
is only an index; no actual SAT questions are included here.
Hint: if you hover your mouse to the right of a face icon, you will see the
answer to that question.
