Yes, the SAT is slightly harder than the PSAT. Both test the same skills, but the SAT has harder Module 2 content and a 1600 ceiling versus the PSAT's 1520.
The PSAT and SAT test the same skills in the same format. The SAT just extends the difficulty range higher — the hardest SAT questions are harder than the hardest PSAT questions.
A PSAT score is a reasonable predictor of your SAT score if you continue prepping at the same pace. Most students add 30–80 points on the SAT compared to their PSAT thanks to extra practice and content exposure.
Do not leave this answer as background knowledge. Connect it to a practice decision: what to drill, when to test, how to pace a module, or how to interpret a score report.
The PSAT is a shorter, slightly easier practice version of the SAT used for the National Merit Scholarship. It uses the same digital format but tops out at 1520, not 1600.
Each SAT section is scored on a 200–800 scale. Your raw score (number of correct answers) is converted into a scaled score via equating, and the two section scores add to your 1600 total.
