PSAT 8/9 prep help
I am preparing for PSAT 8/9 and I bought a book " the princeton review" digital edition book. Now I have completed the book and have done all of its test but when I tried the official bluebook test I got a 1090/1440 (560 english and 530 maths). I want to prepare more but I don't know how. I certainly can't waste my 2nd and last official practice test and I don't see the value in studying the book again. So, any suggestions what is should do?
