With the completion of my last publication, the AP Calculus prep book, all of my math books, including SAT Math, SAT II Math Level1 and II, and AP Calculus AB.BC are now complete. While creating this series of math texts has brought great pleasure to my career, my only wish is that these books will help the many students who are preparing for college entrance. Since 1992, I have had the honor and the pleasure of working with numerous students and realized the need for prep books that can simply explain the fundamentals of mathematics. These books are built on many years of research and experience in each field. Most importantly, the questions in these books focus on building a solid understanding of basic mathematical concepts. Without understanding these solid foundations, it will be difficult to score well on these exams. These books emphasize that any difficult math question can completely be solved with a solid understanding of basic concepts. As the old proverb says, “Where there is a will, there is a way.” I still remember vividly one fifth-grader who was the last in his class who eventually ended up at Harvard University seven years later. I cannot stress enough how such perseverance of the endless quest to master mathematical concepts and problems will triumph. Persistent effort in finding answers to simple and complex mathematical questions is guaranteed to yield fruitful results. You may sometimes find that the explanations in these books might not be sufficient. In such a case, you can email me at firstname.lastname@example.org and I will do my best to provide a more detailed explanation. Additionally, as you work on these books, please notify me if you encounter any grammatical or typographical errors so that I can provide an update version. Per requests from students all over the world who have benefitted from my publications, I am currently working on a video of this series. You will be able to view my classes via internet in 2013. It is my great wish that all students who work on these books can reach their ultimate goals and enter the college of their dreams.
