Will definitely help with preparedness
Format: Paperback, Format: Paperback
When I was first planning on taking the SAT, I definitely underestimated how to be prepared. I wish I had a book like this one back then. This book has really put together a comprehensive way of getting prepared for such an important exam. Not only are there practice exams, there is also a way to estimate your actual test scores so that you can see what areas need work. Also, there are so many different variations of questions that it will really prepare your mind for the actual exam. Better than most practice test books out there.
