This is Part I of the collection of PreCalculus Powerpoint Presentations I developed over my 19 years of teaching PreCalculus. It contains 47 PowerPoint Presentations! Why is SAT in the title? Because these lectures will help tremendously with SAT preparation. Solving MC problems from the SAT book only helps if students know the material really well, and the only thing they need to do is to practice. From my experiences, I know that students first need to learn the material well, and then start practicing from the prep book. My PreCalculus students ask me every year: "What is the best time to take the SAT?" I always tell them: "June, after we are done with the whole year of PreCalculus course." My students who follow my advice and take the SAT after they are done with PreCalculus course mostly get 800 on their SATs.

Testimonials for PreCalculus and SAT Interactive Lectures Vol.1
“From studious memorization techniques to funny, attention grabbing pictures, this book has it all. Through studying with this book, I learned through examples and proofs to know a lot of the concepts of PreCalculus. The memorization techniques helped me a lot on tests when the formula could have gone both ways: positive or negative. Basically, it's AWESOME!” – B.W.
“This is an excellent book! It helps me review PreCalc concepts and has easy to understand lessons for new topics.”  N.Shah.
“Pictures and concise, clear information make this book a great read for selfstudy and review of PreCalc lessons.” H.D.
Excellent learning tool! This was a very helpful ebook with descriptive PowerPoint slides to help me understand PreCalculus more effectively. The example problems were approached in an efficient and analytical way, which left little room for error. The concepts are used in a ways where one doesn't need to memorize a lot, but uses logic and questioning to guide you through the problems. I highly recommend this book for anyone who wants to deepen their understanding in PreCalculus and prepare for the SAT.” K.Nelakonda
“Very Informative! The lectures are easy to understand because they are backed up by proofs, and they provide tips and tricks for memorization of formulas. They’re very effective and helped me get a full score on the SAT II Mathematics Level 2.” Janice
“… easy to learn and understand. I use these powerpoints when I learn something in class and I don't understand. These are also good for test review.” Ju W
“Amazing book! These simple and concise Power Points are not only great for first time learners, but also great to refer back to! …the stepbystep format makes concepts easy to understand and remember. Because of these power points I feel more confident in math, and my scores have reflected that. I highly recommend this for anyone who wants to learn Precalculus!” Happy Student
“Great Teaching Tool! This book is easy to understand, incredibly comprehensive, and greatly improved both my understanding of PreCalculus, and my appreciation for the subject. This book actually got me interested in Math and the possibilities it holds. This book prepared me well for AP Calculus BC and has provided me with a solid, foolproof foundation for advanced mathematics in the future. ” Nic
“This book contains easy to understand lessons that really anyone who has a basic understanding of variable math can understand. It has really made me feel comfortable with the basics of calculus. It also contains interactive examples that have solutions and work shown right after giving a level of enrichment and understanding that most books don't have.” Anish
Perfect for Self Study and Review! The way the lectures are presented provides a fun learning experience for people new to PreCalculus, and a fun review experience for people who has already taken PreCalculus. “モリ・トラ
“The transition from PreCalculus to Calculus BC was easy for me, thanks to Ms. Korsunsky's PreCalculus lectures. Concepts are explained very clearly, and several examples are provided that allow students to easily complete assignments. I highly recommend this book.” – M. K.
Testimonials for PreCalculus and SAT Lecture Notes Vol.1
"Wonderful resource. Very compatible with her Calculus material, so the curriculum flows well. Easy to use workbooks provide powerpoint slides as notes so students can concentrate on listening to lesson rather than writing notes."  Torie Ray, PreCalculus teacher
"This book contains concise and comprehensive lessons as well as examples. I can honestly say that the stepbystep presentations make the concepts both easy to understand and memorable. Because of these Powerpoints, I feel more confident in math, and my scores reflect that! Lectures were great for both first time learning as well as a review source for AP Calculus." X. Yuan
"I used this book my junior year and found it very helpful. The lessons were very easy to follow due to the detailed presentations. This book is very comprehensive and I highly recommend it!" Amazon customer
"This book helped in so many ways, by far the best learning tool in my high school years. I'm currently taking AP Calculus BC, and thanks to the great foundation of PreCalculus I received from the stepbystep notes in this, AP Calculus BC is tremendously easier to grasp. I would strongly recommend both volumes 1 & 2 to anyone who's planning on taking PreCalculus or in already in a PreCalculus class." Selena
"I highly recommend this book because the lessons are presented in an orderly and organized fashion and the content of each topic is thoroughly covered. If you are learning Precalculus, this book is a musthave!" R. Lin
"...This book was a great help for me in preparing for Calculus as well as the SAT Math test ..." Amazon Customer
"I want to thank you for your excellent products. I've downloaded all 4 PreCalc and Calculus courses as well as the Calc AB & Calc BC Multiple choice exams in iBooks. They've been a lifesaver for me as a tutor."  Hanz B.
"Clear and concise, this set of notes really helped present the essential information in a memorable way with good pictures and tables. The step by step instructions are also extremely helpful, letting one know exactly how to solve a problem so there's no doubt. " Victor
"Pictures and clear, concise information make this book a great resource for selfstudy and review of PreCalculus material. All the lessons and chapters are explained and organized well, making the information easy to understand." Nathan C.
"Very helpful if you want to take the SAT Subject Math level 1/2, or just need extra help in precalc. Style of writing makes concepts understandable and clear. Would recommend!" Mei Hsiu C.
"This is an absolutely amazing series of lectures! My son was able to learn so much from them, and ... he was able to score an 800 on the SAT 2 Math Level 2! All of the examples were instructive and interesting, accompanied with detailed diagrams to illustrate the concept. Highly recommended to anyone who wants to have fun learning math!" Mary Chen
