Here is the link to the playlist of videos that explain all of the math questions in the two math modules that are part of the Linear PSAT Practice Test 2 released by Collegeboard in September 2024.

Please note that there is a significant overlap in the questions present in the Digital Bluebook version of the PSAT Practice Test 2 and the Linear PSAT Practice Test 2. The following math questions in the Linear PSAT Practice Test 2 do not appear in the Bluebook version of the Digital PSAT Practice Test 2: Module 1(Question#13, 21, and 25); Module 2(Question#11, 23, 24, 26, and 27). I recommend that you take the digital PSAT first and then only use the Linear PSAT for additional practice.
