MASTERING AMC 10-12 & OLYMPIAD CHALLENGES: GRADES 8-12

I only did the first (of eight) tests but of the 12 questions, the answer key got 7 of them wrong! For example:3, 33, 333, 3333.... is a geometric sequence with a common ratio of 10. What!!! That's stupid.Box contains 5 red balls, 4 blue and 3 green. Probability of pulling 3 red balls same as 3 blue or green. NO!!!The expression 3x^3-4x^2+5x-2 can be divided by (x+1) w/o remainder. NO IT CAN'T!!This book is a complete rip-off. DO NOT BUY THIS!!

This book is consisting of 10 practice AMC 10/12 tests. It contains a great many original problems. I also loved the quality print. All in all , I love it. I highly recommend it for the AMC 10/12. Students who need further practice must completed this book before the exam.

Should be zero star.This book is full of mistake. It’s misleading. It’s waste of time and money.No buy!

We are immensely grateful to everyone who took the time to review the book. It is through the collective efforts and contributions of all involved that the book can truly reach its potential and be a remarkable piece of work

The problems are too easy. Yet somehow the answer key has an insane number of mistakes!! I only did the first 6 problems in the book and of those - THREE were incorrect!! Unacceptable!

This book is not only useless but harmful. Only after going through the first part of the book, we found that some questions don’t make sense and that some explanations are wrong.

First test’s problem #1 has wrong answers in the options.So many mistakes on the answer book.Don’t buy it….

Answers are mostly wrong. Most of the solutions are misleading. Lots of silly mistakes
