The College Board has made a comprehensive Digital SAT Question bank available on their website:
https://satsuitequestionbank.collegeboard.org/digital/search
You can select certain question types, like Rhetorical Synthesis or Transitions, and create a PDF document that features those questions. It looks like many of the questions are repeats from the Bluebook SAT tests and the Khan Academy questions, so be prepared to have some overlap between the questions in this database and the questions in those other resources. Even so, this will be a valuable tool for students trying to prepare for the Digital SAT and Digital PSAT.
