Foundational Skills

Our approach to the SAT is two-fold. We help you from the bottom up by strengthening your foundations in every aspect of the test (reading comprehension skills, vocabulary enhancement, writing skills) and from the top down with test-taking techniques.


Quality Test Prep

We do not overload you with busy homework or waste your time in class doing unnecessary exercises. We believe in quality not quantity. Every teacher, every course packet and every minute you spend with us will ensure the highest quality preparation money can buy.


Maximum SAT Score

Everything we do here is designed to help you get a higher Digital SAT score. We understand that your time is in short supply so we designed a curriculum that will give you the maximum results in the shortest amount of time.


Winning Technique

For 20 years we've compiled fastidious notes about curriculum content, specific test material, the strengths and weaknesses of various education levels and school systems, and the reasons students were having a hard time with the SAT. 


We developed, through hands-on experience, step-by-step techniques for each section: Reading, Writing, and Math. Eventually, the winning IES curriculum and techniques were born.

A Replica of Princeton

I come from an international business family and when I was a student at Princeton I developed close relationships with my favorite professors. On one occasion I hosted the Chairman of the Princeton History Department at my family’s ranch in Kenya. He was doing research in African history and I was proud to introduce him to some key figures in African society whom I knew well. When I graduated in 1988, seven professors attended my private reception party. We held interesting academic conversations about world affairs. Like many of my classmates I entered the world of international finance, received my MBA in 1991 and pursued a career in business. But I always desired to build an academy to re-create the spirit of my Princeton experience. I wanted a place where students could feel close to their teachers, respect them as mentors and not fear them as authorities. I am very proud to say that I have succeeded in creating this academy as a small replica of Princeton in which there exists a camaraderie among students and teachers. I feel proud when I see students and teachers talking in the student lounge or on campus grounds between buildings. IES teachers are involved in every aspect of student development: tutoring, mentoring, guiding. Students stay long hours at IES taking advantage of every service, such as workshops. IES students are very well behaved and academically competitive. Their SAT scores are increasing every year.

Test Preparation


IES Test Prep (formerly IES2400) has been providing top-quality SAT prep to students in NJ and NY since 2003; many of our students perform well enough on the SAT to gain acceptance into Ivy League universities, some with perfect scores. 

Our approach to the SAT is a combination of technique and practice. Technique is taught during a 4-hour lesson (usually 9am-1pm), and practice follows by way of a 3-hour workshop (usually 2-5pm). Experienced teachers convey specific steps to be used on each part of the test - reading, writing, math. 

IES Test Prep has been preparing for the SAT change-over ever since the College Board announced it in mid-2014. With the help of a teacher-led team of full-time writers and editors, we have amassed ample practice tests and coursework. We strive to replicate the exact difficulty and nature of the real SAT so much so that our student scores vary by no more than ten points when their real scores are compared to their practice scores.

SAT Preparation at IES Test Prep

Standardized tests require a standard and precise curriculum. All IES SAT prep classes are run following the same curriculum. The SAT is a difficult and tricky test for which no adequate preparation currently exists in high schools. It is a specialized test that requires a specialized approach in which school teachers are not trained.

Every individual has different scheduling needs. As such, IES offers a wide array of courses that meet either once a week, twice a week or, as in summer, 4 times a week. Regardless of the schedule, each course teaches you how to spot and use the clues provided in the SAT test to maximize your accuracy, speed, and confidence.


The SAT math section covers 50 topics that the College Board deems necessary for both collegiate success and post-graduate workplace readiness.  The IES mathematics curriculum is teaches skills that address each of these topics, and an additional set of general test taking skills that can help in a variety of situations. 


Evidence-based reading, a feature of the SAT, tests your global comprehension of a passage as well as your attention to particular details. You may be asked how a particular paragraph functions in the overall context of a passage, the meaning of a word, or the stance of the author.  At IES, we teach the steps to solve and conquer these questions, through a series of class lectures, and intensive workshop practice. 


“Who” or “whom”? Comma or semicolon? Indicative or subjunctive? These are only a few of the questions you’ll face while navigating the murky, confusing, and sometimes downright tedious obstacle course we call SAT Grammar. Luckily for you, we’ve done all the hard work already and condensed hundreds of years of complex terminology and obscure Latin-based rules into 18 straightforward, easy-to-remember guidelines. 


Students who have completed a full SAT course are eligible to register for the IES  Bridge, a private lesson package that includes weekly practice tests and workshops. The purpose of this program is to provide follow-up, individualized prep during the time period between the end of an SAT course and the official test date - the "bridge". You may select the number of weeks you wish to include in your bridge, as well as your preferred area of focus (English, Math or both).

IES Publications


Your Education is Our Top Priority!
Here at IES Publications, we want to give you the confidence you need to control the test. 
Together, we can make your Test Day a success!

IES Publications is a consortium of writers, editors, teachers and test prep coaches who have all put their heads together to reverse engineer the SAT and ACT. At IES Publications, we strive to create material that will meet the standards of our discerning audience. Working in tandem with IES Test Prep, a test prep academy that tailors its courses to the most advanced students, we noticed a marked gap in test prep material that would satisfy our elite student body. Based on the popularity of the work we have already published for use in our classes, we thought, why stop at just our students? With a staff of writers, editors, and educators, and with a wealth of research and development about the SAT behind us, our material stands tall above the rest.
