Thank you Dr. Gruber, I improved my score using your great instructional material and strategies. Without any of your preparation or advice, I got 950 which is about what I got on my actual SAT at that time. After reading your specific advice on how to improve after each test, I increased my score steadily on each upcoming test. By the time I got to the last test in your book, I scored 1520. Before taking the actual SAT I brushed up again and got 1580 on the actual SAT – only 20 points shy of a perfect SAT score! I am convinced I could not have achieved such a great final score, and going from a 950 to the 1580, without your help!
