We use Google Meet for face-to-face interaction and screen-sharing, as well as an online whiteboard where we uploads photos of worksheets, post PDFs, and see each other’s writing in real time.

* MY APPROACH *

Focused and encouraging, enthusiastic and personable, I've helped students reach that "light-bulb moment" countless times. I've got your back! Content knowledge is only part of the puzzle, though; problem-solving skills are crucial, so I share tactics on being methodical and help in constructing a system. Check my testimonials to hear from my students!

Effective tutoring is not a one-off, stopgap solution; I often end up working with my students long-term, through their high-school and early-college years.

* BACKGROUND *

Attended Princeton for molecular biology. Completed the IB program as salutatorian out of 500+.

Tutored since HS (2004) in a variety of subjects. Mostly students in grades 6-12 or college / grad school. In Chicago since 2017, I've worked with students in CPS, Latin, Parker, Northwestern, and more.

Highlights: 800 SAT Verbal and SAT Math Level 2; 740+ on other SAT sections and Subject Tests; GRE - 164 Verbal, 169 Math; 5 on AP Bio, Chem, Calc, U.S. History, English Lit, and Spanish.

Certified in Teaching English as a Foreign Language (TEFL); co-instructor at a private university in rural China for 3 months.

Approved Subjects

Algebra 1

Algebra 1

I took Algebra 1 in 7th grade and completed high-school math through AP Calc BC (Calculus 2), earning an A every quarter. I also took multivariable calculus and linear algebra in college. I graduated from the IB program, taking HL Math, so I'm familiar with the British curriculum (IGCSE, A-levels).
Algebra 2

Algebra 2

I took Algebra 2 in 9th grade and completed high-school math through AP Calc BC (Calculus 2), earning an A every quarter. I graduated from the IB program, taking HL Math, so I'm familiar with the British curriculum (IGCSE, A-levels).
American History

American History

I took AP U.S. History in 11th grade (score: 5).

Biology

I majored in molecular biology. I took Biology Honors in 9th grade and AP Biology in 12th grade (score: 5), as well as biochemistry, genetics, and cell and developmental biology in junior year of college.
Calculus

Calculus

I scored a 5 in AP Calculus, after earning an A every quarter. I graduated from the IB program, taking HL Math, so I'm familiar with the British curriculum (IGCSE, A-levels). I've tutored several high schoolers and college students successfully in AP Calculus AB, AP Calculus BC, Calculus 1, and Calculus 2.
Chemistry

Computer Science

Computer Science

I scored a 5 on multiple AP Computer Science Principles mock exams (it didn't yet exist when I was in high school!), mastering the material through exercises, typical projects, and practice tests. Being self-taught means that the explanations, analogies, and mnemonics that I teach students are "tried and true" -- they helped me personally, so they've been vetted!
English

English

I was known as the Walking Dictionary in grade school! I scored an 800 on the verbal section of the SAT. I took AP English Literature in 10th grade (score: 5) and AP English Language & Composition in 11th grade. I also taught English to community college students in China in summer 2011.

In high school, I took two years of biology (including AP Biology), three years of chemistry (including AP Chemistry and IB Chemistry III), and two years of Physics (including AP Physics B). In college, I majored in molecular biology, and have taken courses in physics, biochemistry, and neuroscience. In tutoring physical science, I focus on not only knowledge but also techniques for study and retention (outline skills, mnemonics, spaced repetition).
Physics

Physics

I've tutored dozens of students in algebra-based physics, such as high school physics, AP Physics 1, AP Physics 2, and intro college physics. I don't tutor AP Physics C (calculus-based), though I do tutor calculus itself (e.g., AP Calculus AB or BC). I got straight-As in the equivalent of AP Physics 1 and 2 in 11th grade (it was one exam called AP Physics B), as well as in two semesters of introductory physics in freshman year of college.
Praxis

Amazing tutor

My daughter literally said “I have aha moments when Stephanie explains chemistry. She not only asks for the answer but then asks why? I didn’t know why, so she made a chart explaining the why and it made so much sense.” My daughter has been able to understand previous material and feels confident getting ready for her final. I highly recommend!

Knowledgable & patient tutor

Stephanie is working with my daughter in the days leading up to a grueling week of 6 IB exams. She stepped right in to help with some of the trickiest concepts in both IB Math & IB Chemistry. She's made time for us and wasn't daunted by the urgency of our needs. Tutoring is patient and helpful and both supports and challenges my daughter's learning style. Very gratful!

Patient and extremely helpful

The class was absolutely perfect. She was able to teach me what I had done wrong in my exams as well as how to come upon the right answer for that question and for any other that was similar. The pace of the lesson was perfect and really allowed me to understand and use the new information I had just learned.

Incredibly helpful

My high school daughter has finally been learning everything she needs in chemistry thanks to Stephanie - making a huge difference! Definitely recommend her - very patient and we see the results!!

Angela, 21 lessons with Stephanie

Very promising first session

First session was great. Stephanie was perceptive about what my daughter didn't know, and what she needs to do to get up to speed. Very comfortable with the material--10th grade chemistry. Spent a lot of time with her to get her ready for a quiz. My daughter immediately responded positively to her teaching style.
