SAT Math — Hard Mode Mock Test

What this mock is for

Every question below was chosen because it's one Korean students consistently miss — not because it's obscure, but because it hides a trap: a sign error, a misread condition, a step that looks optional but isn't. If you can clear this set cleanly, nothing on test day should surprise you.

Directions

• The graphing calculator (Desmos) is available the entire time — click the Calculator icon in the top bar.
• Use Mark for Review to flag a question and revisit it later from the Review Page.
• A Reference Sheet with standard formulas is available from the top bar.
• You may move freely between questions using Back / Next or the question grid.
• The timer can be hidden, but it keeps running in the background.
