Here's a guide that I've written from the help of many people who have scored in the 1500-1590 range in the New SAT!
Scroll to the end for a link to most of these books and resources!
I would be really thankful if someone would share or upload eBooks/PDFs for the New SAT (preferably Barron's, Princeton, or Kaplan) and some helpful resources, websites, notes, and etc as well. Thank you! :)
