SAT Math — Hardest Questions Mock Exam

This module has 22 questions to be answered in 35 minutes. All questions in this module are drawn from the highest-difficulty tier of Digital SAT Math and are the categories Korean students most frequently miss.

• For multiple-choice questions, select the single best answer from the four choices.
• For student-produced response (grid-in) questions, type your answer as an integer, decimal, or fraction.
• You may use the built-in Desmos graphing calculator on every question.
• Use "Mark for Review" to flag questions you want to revisit before submitting.
• Use the answer eliminator (✕ icon) to cross out choices you've ruled out.
• Unanswered questions are not penalized — always submit your best guess.

Once you click Start Module 1, the timer begins immediately.

Module 2 continues with 22 more of the hardest question types — nonlinear systems, 3-variable elimination, law of cosines, logarithms, and rate/mixture problems. Same rules apply: 22 questions, 35 minutes.

• Your Module 1 results are locked in — you cannot go back and change them.
• The Desmos calculator and reference sheet remain available throughout.
• Pace yourself: about 1.5 minutes per question, but hard questions may take longer.
