@salma45, both of my daughters took the SAT a few weeks before the PSAT - that is totally fine. You can find prep materials for the PSAT here and on Khan Academy’s website: https://collegereadiness.collegeboard.org/psat-nmsqt-psat-10/practice. Collegeboard also sells SAT prep books through bookstores, probably their website too. It’s called The Official SAT Study Guide. Make sure you get the most current version.
