"The new PSAT 10 and SAT Math sections are much harder. This workbook is the only one of the three that I have that provides foundation and practice for Extended Thinking problems and Radians in dedicated lessons. Without having a good understanding of problem solving techniques you will either get the problem wrong or you will waste a lot of time . This workbook prepares you to crack the test with comprehensive treatment of extended thinking, trigonometry, radians, and complex numbers - topics that are new in the new PSAT 10 and SAT. Very precise and sharp workbook."
