I think George is not merely a tutor – he is a real educator. He knows that what helps students perform well on tests is the same as what makes them good students. A solid academic foundation pays dividends throughout schooling and careers, and George never loses sight of that in his work.

SAT & ACT Preparation:
Perdocere is proud to provide by far the best math preparation for the SAT, ACT, and SAT subject tests. Teach the required material, drill practice exams, detailed decomposition of and solutions to problems, expose underlying themes, question categories, time management, and test taking strategies. Perdocere takes a unique approach to teaching the math portions of these tests – Perdocere actually teaches the math! No tricks that try to replace learning and comprehension, no gimmicks with fancy names, no relying on memorizing formulas. High scores are earned through a combination of the best tailored instruction, diligent work by the student, developing proper problem solving and test taking skills, and drilling practice exams. Perdocere students consistently achieve superior scores and develop creative problem solving skills for success now and in the future.

Whether to take the SAT or ACT?
The most certain way to determine whether a student has a propensity for one test over the other is to take a separate practice test for each. Perdocere not only analyzes the results of these practice tests, but assesses the abilities and capabilities of the student by direct observation during the examination process. It is usually straight forward to then determine which test is better suited for the student. Single tests that attempt to determine this propensity suffer from a lack of consideration for a wide variety of factors. The math portions of the SAT and ACT are distinctly different and require very different preparation.


“Thanks to George I am getting an A in honors pre-calculus. Not only am I understanding the material fully, I find myself thinking outside the curriculum and trying to learn more advanced math. Only George could have taught me this high a level of math, and he is currently preparing me for advanced placement BC calculus. I am 100% confident George will help me conquer that class too.” (800 SAT Math, 800 SAT Math IIC, 36 ACT)

“800 – we thought that sort of score was something unattainable – something that only a few gifted students achieved. And now our son (who we love dearly but never considered to be a particularly gifted math student) has brought home 800’s twice – once on the SAT and once on the SAT II. We attribute so much of this achievement to George. He restructured fundamentals and taught our son to enjoy math once again. George consistently challenged and pushed – but never too much. He displayed patience and a wonderful gift for explaining things. As our son told us, George not only works through problems but teaches how everything evolved and why everything is what it is. We couldn’t ask for a better teacher. We really don’t have enough adjectives to describe George’s teaching ability. He is absolutely the best teacher that we have ever seen!!! George – your job with number one son is almost done – it is now time to move to number two.”

“I met George in February of my junior year. Earlier in my junior year and sophomore spring, I had been bounced between countless math tutors who seemed uninterested in actually changing the way I learn and comprehend math on different levels, which is a necessary transition from my school math course work to solving problems on the ACT. A few had deemed me incapable of ever truly raising my math IQ and relied heavily on strategy to get me through standardized testing problems. Yet with George, everything changed. He studied the way I learned and took tests, and synthesized the information I gleaned from each of our sessions. He then broke down my entire bank of knowledge in the realm of mathematics and we started from the bottom, building our way up. As each new brick was laid in the foundation, my confidence grew and my ability to take control of the ACT in a way that worked for me was apparent. I no longer fear ACT test day, new units in Pre-calculus or a problem that seems overwhelmingly difficult based on its exterior. George became my math savior and I can not thank him enough.”

“George works miracles! When I first started with George, I took a practice SAT and sadly got a 550. George explained that he was going to rebuild my math knowledge and rewire how I looked at math problems. Over the course of the summer and fall, George continued to work with me and with his careful instruction, guidance, and support I was able to get a 780 on the real SAT. George taught me to think differently and to approach math problems in creative ways. George pushed me to be the best student I could be, but never pushed me in a way that was counterproductive. Though I was not confident at the start, George’s never ending encouragement and faith in me allowed me to finally recognize my full potential in the SAT and in my math classes at school. I can’t thank George enough!”

“George is the best tutor that our family has ever used. No one else is even close. He quickly identified my son’s strengths and weaknesses, and then set about in an orderly, sensible and strategic way to fix the weaknesses. There was a purpose to every problem set or test that he assigned.  George customized his approach to the individual child which in turn created ‘buy-in’ from my son, who realized that he was not going to be assigned busy work, but focused problems designed to address areas that needed work. Bottom line my son got a 55 on the PSAT math and eight months later, with George’s help, got a 770 on the SAT math.”
