A couple of quick examples:
Test #4, Section 1 (Reading), page 679, line 56. The sentence is missing a verb after the comma (“comes” would be my best guess).
Test #4, Section 3 (Math No Calculator), page 769, answer explanation for #11. Should say -49, not -54 (they forgot to add the 5). It doesn’t affect the correct answer, but it’s a mistake all the same.
It’s nothing major, but it’s clear to me these New SAT questions are a bit less polished than usual.
