Sorry Jdent I LOVE DESTROYER, but the math section is to easy. You should be able to AT LEAST do those problems. Secondly that wont help you with timing. I got crack math and was surprised that my first test took me 55 mins to complete. Within three tests I got my timing down and consistently finish in time now after practicing pacing which of all sections is probably most important in this one. I think crack math is a great resource. The explanations (if you can even call them that) do REALLY stink though but its good practice.
