About Corey

I believe that everyone can achieve great goals and make the world a better place. I believe that many people would, if not for obstacles or misfortune they’ve encountered, often through no fault of their own. Finally, I believe that I can help these people overcome their obstacles and realize their great potential.



How I Help

When I tutor, my job goes beyond helping a student pass a test.

Every topic we learn, we review and build on the fundamentals that came before. Many students today are victims of a test-obsessed education system that teaches them how to pass their next test, but not how to understand and apply the material to future lessons. As a result, many students start to struggle with subjects they once enjoyed, and they can’t figure out why. Often, the student actually understands the current topic, but gets the wrong answer because of simple mistakes on material they were supposedly taught long before and that their teacher just assumes they already mastered. By rebuilding a solid foundation of fundamentals as we learn new topics, we don’t just pass the test; we revitalize the student’s confidence.

Every topic we learn, we also practice skill of learning. Learning should be a life-long pursuit, yet our education system never explicitly teaches students how to learn. When I tutor, “How to Learn” is the most important lesson. Every session, we go beyond how to solve questions on a test; we practice thought experiments and abstract reasoning, and we connect the current concept to principles from past lessons and “sneak peeks” of future material. When I do my job, and when the student puts in the work, the student becomes a self-sufficient learner who no longer needs me.

I recently checked-in with a former student’s mother, just to ask how he was. I did not ask for feedback, but I got the following response:

“Tristan does really well. He just started his junior year [in college]. Time is really whizzing by! Currently a cumulative GPA of 3.989. I strongly believe the reason he does so well (other than working hard, which he does) is due to your help at the right time. He thinks very highly of you and often mentions just how much you’ve helped him, and how much he enjoyed working with you. Math and science became his favorite courses after you started teaching him. I only regret one thing, and that is that we didn’t’ know you sooner. I would have let you teach him all his middle and high school math and science courses!”



What I do

I graduated from the University of Pennsylvania in 2012 with two degrees, with honors: a BSE in Chemical and Biomolecular Engineering, and a BSE in Undergraduate Business from Wharton. Since I started tutoring in 2012, I’ve spent more than 2000 hours tutoring students of all ages (from 11 to 46) 1-on-1 across a wide variety of subjects and levels.

If you have trouble with any of the following subjects, I can help.
•Math, including Pre-algebra through Statistics and Multi-Variable Calculus
•Science, including Physics, Chemistry, and Organic Chemistry with Calculus
•Business, including Accounting, Finance, Economics, and Operations
•German, including business and economic vocabulary
•Standardized Tests, including the SAT, SAT II, ACT, AP, GRE, LSAT, and GMAT

If you need help, message me. I will get back to you within 24 hours, and we can schedule a lesson to make sure I'm a good fit for you or your child.

Sincerely,

Corey Lerch

Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Algebra 1

Algebra represents a fundamental transition and new way of thinking for every math student. Many students, myself included, needed some help making that transition, but once it's made the subject can be surprisingly easy. I think it's my job to help the student understand how to think so eventually, they learn the material on their own with ease.

Algebra 2

I took Algebra II (Honors) in my freshman year of high school and passed with high marks. I've also had a lot of practice since then, since I faced a lot of algebra-intense problems in the physics and engineering classes I took at UPenn.

Calculus

I took two years of calculus as a high school student and another 3 semesters in college. I struggled with calculus for a while before it "clicked" and I started to understand it intuitively. I've also had a lot of practice sharing that understanding with my peers. I think Calculus is when a student truly starts to understand how elegant math can be.

Chemical Engineering

I earned a BSE with honors from the University of Pennsylvania (Ivy League) in Chemical and Biomolecular Engineering. As part of my senior design project, I used the accumulated knowledge to design a complete process, simulated in ASPEN, for the renewable production of para-xylene from biomass.

Chemistry

I studied Chemistry in my Sophomore year of high school, and I had one of those teachers that changes your life. I took AP Chemistry in my junior year, passed the AP exam with a 5 (highest score). I also qualified for the National Chemistry Olympiad at the state level twice (top twelve high school chemistry students in the state). I went on to study Chemical Engineering at an Ivy League school. I've also tutored Chemistry before at the request of my high school chemistry teacher.

Elementary Math

I believe Math is the most important subject for a young student. Beyond setting the groundwork for more advanced math later, it teaches the problem-solving and pattern recognition techniques that every subject needs. As a result, I believe a tutor should focus on the underlying problems and patters in the math rather than the rote memorization that will only help the student pass their next quiz.

English

I have two undergraduate degrees from the University of Pennsylvania, with one semester of Writing Seminar included in the curriculum (passed with an A-). I also scored 740 and 680 on the SAT Writing and Reading sections, respectively, while in high school. I'm particularly well-suited to teaching grammar, since fluent command of German requires mastery of grammar concepts we tend to take for granted in English.

Finance

I have an undergraduate business degree from Wharton Business School, including 2 semesters of education in Finance. I also carry Series 6 and 63 securities licenses from FINRA.

Financial Accounting

I studied both financial and managerial accounting at Wharton Business school as an undergraduate. I also taught the whole managerial accounting course to my roommate at the time, so I have practice teaching the material in a way that makes sense to the student.

Geometry

I took Geometry in 8th grade. Of all fields of mathematics, I find Geometry most intuitive. Because of that, I have a lot of practice conveying that intuitive understanding to my peers.

German

I've studied German for 10 years, starting in 6th grade and including 4 semester of study in college. I passed the German AP exam with a score of 5 (max is 5). I also studied abroad for two months in the Summer of 2011.

GMAT

I graduated from Penn's Wharton Business School and School of Engineering with 2 honors degrees in 2012. Between the two degrees, I can confidently teach you to handle all sections of the GMAT: Verbal, Writing, Reasoning, and especially Quantitative.

Macroeconomics

I have a Bachelors Degree from Wharton at UPenn in undergraduate business, with 4 semesters of study in Economics, including 2 honors courses. I earned an A or A+ in all 4 courses.

Managerial Accounting

I studied both financial and managerial accounting at Wharton Business school as an undergraduate. I also taught the whole managerial accounting course to my roommate at the time, so I have practice teaching the material in a way that makes sense to the student.

Microeconomics

I have a Bachelors Degree from Wharton at UPenn in undergraduate business, with 4 semesters of study in Economics, including 2 honors courses. I earned an A or A+ in all 4 courses.

Organic Chemistry

I graduated with honors (GPA >3.4) from the University of Pennsylvania (Ivy League) with a degree in Chemical Engineering. Curriculum included two semesters of lecture and one semester of laboratory organic chemistry. I've tutored 4 students in Organic Chemistry so far, all of whom used my services on a recurring basis throughout the semester.

Physics

I have a degree in Chemical Engineering from the University of Pennsylvania (Ivy League school). Curriculum included two courses in Physics, both passed with grades of A and A+. I've successfully tutored physics for multiple students on a recurring basis.

Prealgebra

I took Prealgebra in 6th grade. Though I'd always been a strong math student, I struggled with the transition to the higher level concepts. I overcame that lack of intuitive understanding, however, and went on to a fruitful study of mathematics up through six semesters of calculus. I believe I can help a struggling student make the transition from arithmetic to higher mathematical concepts.

Precalculus

Precalculus may be the most important year of math high school students take. As an engineering graduate, commanding calculus was critical for my education. However, I saw many intelligent peers struggle with math not because they couldn't understand the calculus, but because they lacked strong precalculus fundamentals. I believe that once students establish that strong base in precalculus and learn to apply it to the more complex concepts, they tend to succeed in precalculus and beyond.

Probability

If a situation is repeated again and again, the observed proportion of successful outcomes will tend to approach the theoretical probability that any one of the outcomes will be a success

SAT Math

I took the Math SAT twice without any preparatory classes, scoring 780 and 800. I also scored 800 on the Math SAT II. I believe the secret to success on the Math SAT is solid fundamentals, pattern recognition, and understanding the questions.

Statistics

I graduated from the University of Pennsylvania (Ivy League) with Honors (GPA >3.4) with a degree in Chemical Engineering. Math curriculum included 2 semesters of instruction in statistics and probability, both passed with grades A- or higher. I've successfully tutored several students in statistics on a recurring basis.

Trigonometry

I graduated from the University of Pennsylvania (Ivy League) with Honors (GPA >3.4) with a degree in Chemical Engineering. Math curriculum included 4 semesters of calculus and two of statistics and probability. I've successfully tutored multiple students in all math subjects through and including calculus. I also scored 800s on the Math SAT 1 and 2, and 5s (max 5) on the Calc AB and Calc BC CollegeBoard AP exams.

Really good at creating intuitive understanding

Corey helped me succeed in my introductory Statistics class at Duke. He helped me nail down the basics of statistics and create an intuitive understanding of the topic, which helped me improve my grade drastically. Very nice, knowledgeable, intelligent, and communicates ideas well. Helped me work through problems, no matter how long it took me.
