Old SAT Practice Tests vs Prep Books

Hi everyone. I’m coming close to completing the eight official practice tests in the college board official study guide. Would it be better to practice with pre-2016 official tests or use a prep book for the new SAT? Which prep book practice tests are the most realistic to the actual test? Thanks.

Google (especially reddit) to find links to more recent QAS exam copies that have been uploaded. There are about five exams.

I would not use Old SAT material.

If you exhaust the Reddit materials, you should just order a new book. Don’t go back in time to older SATs to take practice tests, especially the 2400 scaled ones. Stick with the current format, and buy the new books.
