Divergence between khan academy mock marks and the real sat marks

Test Preparation

Just wondering how much does the khan academy mock differ from the real sat in terms of difficulty and how by how much does the real test’s mark vary from that of the mock’s

DS took the khan academy SATs and scored 1590 on them but 1550 on the actual exam. Still a great score and hopefully he is done.

The khan academy tests are real college board tests.

My actual test results were more or less the same as my Khan Academy test results (10 points higher, actually). Every time taking the test is different and not perfectly predictable (additional pressure on the test date, etc), but I think Khan Academy scores are good predictors of SAT test date scores.

I averaged around 1520 on the Khan tests and pulled a 1550 on the August 2018 test.
