What are some other SAT practice resources (maybe more challenging) than Khan Academy after I have completed level 4 questions in certain skills but still want to practice more?
google-there are tons out there. However, my kid finished all of the level 4 lessons and you can go to subjects and select there. There is more than you may realize.
@Center Thank you, but actually I’m looking for truly qualified sources based on experiences of others. No one wants to spend his/her precious time on unappreciated and impertinent materials.
@TTNL2405 no no one does but you are not likely to get one answer to your question. Some swear by Barrons, Kaplan, Princeton, Khan and the numerous other prep websites and books.
