In your experience, are the SAT practice tests on khan easier or harder than the real thing? Thanks!
My son found that the SAT practice tests were a decent prep tool for the real deal. His test may have had slightly more challenging math and reading questions but the curves adjusted to accommodate that.
Like for the ACT, one should always be prepared for some curveballs on SAT test day, so while the practice tests can be excellent prep it’s best not to get too comfy with how you are doing on them. Strive for 100% correct in practice so you won’t have to worry too much about the real test.
