I borrowed this book for practice to retake my ACT. Some of the strategies are actually okay. The problem is the practice exams. The answer explanations that the give really don't make sense and are debatable. I suggest Barron's or the Princeton Review as opposed to this book.

I am begging you not to buy this book, I am a highschool junior trying to prepare for The ACT's so I was taking the Diagnostic Test at the begining of the book and in checking my answers I realized that I had WAY too many wrong answers, so i checked the Answer Explanations for one of the questions I got wrong, the question was and I quote "The original price of a computer was $1200. What was the price of the computer after two 10% mark downs?" F. $960 G. $972 H. $980 J. $1,000 K. $1,072 The correct answer would be of course G. $972. So I went to check my answers in the back of the book and it tells me the correct answer is F $960. I dont understand how this is possibly true so I go to the Explanations where it says (and again I quote): "Marking down $1,200 by 10% reduces the price by 10% of 1,200=120. The new price is 1200-120=1080. Marking that down 10% reduces the price by 10% of 1080=108, so the final price is 1080-108=972" This is answer G not F!!
