The fact that this book contains a formidable 15 exams, dwarfing its competitors in the sheer number of tests offered, alone makes this book a valuable purchase for somebody seeking a VERY high score on the Math IIC. If your target score is not above a 750, this is not the book for you. I am a very good math student and could not finish a single exam, and my highest score was a 700 flat. I highly recommend buying this book in tandem with Kaplan Math IIC. Kaplan is notoriously easier than Barrons or Princeton (neither of which are as hard as this). Do as many Meylani tests as you can, then with 5 days before the exam, do a few Kaplan exams to get your confidence up, as Kaplan is largely accurate to the actual exam. Using the Meylani was very helpful to me, and made the actual exam seem significantly easier than it would have been otherwise.
