About this tutor

I offer a wide range of math and statistics topics. I hold a BS in Mathematics, a MS in the computer science, and a PhD in  biostatistics from Harvard University. I have tutored many students having a diversity of backgrounds and needs. I live in Cambridge close to Harvard College, and could  arrange student participation in some relevant events and workshops there if desired.  

Helping people of all ages to develop mathematical/statistical thinking, problem-solving, and intuition, and that "Ah, ha!" moment from my students. Also see the “What is your typical process for working with a new student?” section later on.

    Nicholas Lange is an incredible tutor and I recommend his services to everyone. Nicholas has an extensive background in statistics and offers an individualized approach for those in need of math assistance. The best decision I made regarding my academics was working with Nicholas on college-level statistics. My experience has been nothing short of exceptional. At the beginning of the semester, I was struggling with statistics and needed urgent help. Nicholas and I were able to instantly start working together to prepare for my exam. I saw immediate results and could not believe how much material I learned in such a short time frame. During this period, I had his complete attention, priority, and flexibility both during and outside of our sessions. Nicholas instantly recognized the type of material I was working on, created an individual action plan, and most importantly, taught me how to master my course material. As I continued to work with Nicholas over the course of the semester, I was able to build on my statistics knowledge. These weekly sessions continued to build my confidence and provided me with a comprehensive understanding of statistics. I can attest that Nicholas goes above and beyond each session and is truly an excellent tutor.

    Nick was a fantastic tutor on many different levels. First, he took time to understand exactly what my goal was, and then tailored a plan specifically to help me achieve my goal. For me, this was passing the Executive Assessment in a tight time frame, which I was successfully able to do with his help. Secondly, after understanding my goal and creating a tailored plan to help me achieve it, the actual tutoring sessions were extremely valuable. Nick is a great communicator and teacher of math. Very quickly he was able to understand the nuances of how I learn new concepts, and adjusted his teaching style to fit my comprehension style. Without this, I doubt I would have been able to pass my test. Finally, Nick is just an all around great guy. It was always relaxing and fun to work with him, and I would not hesitate to recommend him to anyone looking for a great tutor.


What is your typical process for working with a new student?

It's all about meeting the student where he or she is, and bringing them forward step-by-step. Here’s how I do it I frst obtain a general sense of a student as a person. I then learn about the student's learning attitude and background in math. Knowing this, I then make a few checks to gauge what the student knows. For instance, "What is 9 X 17?"; "Solve 2X - 5/3 for X" (or a more difficult equation in X); "What is a prime number?"; “What is a right triangle? Give me an example“;  “Are these two triangles similar? Why, or why not?”; “How does one solve two simultaneous equations with two unknowns?”; "Give me a simple example of the general linear model?". I also use my "function box", which is a picture of a "black box" with input and output funnels with a few numbers going in and out after the inputs are processed by the unknown function inside the box. For instance "4, 5, 6" yields "8, 10, 12", (doubling) or "1, 2, 3, 4, 5, 6" yields "0, 1, 1, 3, 5, 8, 13" (the first six elements of the Fibonacci sequence; if correct  mand if the student is interested, I'd show examples from nature such as sunflower spirals, chambered nautalus, the Parthenon, the Mona Lisa). I then proceed to teach the student  how to use symbols (such as X, Y, Z), pictures, and formulas including numerical examples of each. I work from the student's textbook, if any. I assign homework and quick quizzes of 2-3 questions at the beginning of each session.

What education and/or training do you have that relates to your work?

I hold a BS in Mathematics, MS in Computer Science, and a PhD in Statistics. I've taught students at elementary, middle, and high school, undergraduate, graduate, and Phd and MD levels privately and in formal classes. I love teaching students at all levels. See previous descriptions for more.

Do you have a standard pricing system for your lessons? If so, please share the details here.

Rates depend on student background and specific needs. For instance, my rates are usually $50/session for elementary and middle school students, $60/session for high school students,  $70/session for undergraduate and graduate students, $80/session for professionals. 

How did you get started teaching?

I started tutoring math as an undergraduate to middle school and high school student. I helped students in my undergraduate and graduate classes; one undergraduate student really needed help in symbolic logic and improved her grade in the class; one graduate student needed help in linear algebra, and had the same results.

What types of students have you worked with?

Elementary, middle school, and high school students; undergraduate and graduate students; PhDs and MDs.

Describe a recent event you are fond of.

I once had a high school student who was highly motivated and eager to learn. She asked exellent questions, did her home work, and was a quick study. She told me she learned a lot, and her parents were gratified they received my help.

What advice would you give a student looking to hire a teacher in your area of expertise?

I advise students to tell me their goal(s); have a clear understanding their math background; describe any general or specific issues that are arising; prepare some key questions about me; be enthusiastic! 

What questions should students think through before talking to teachers about their needs?

As in the preceding question: What are your goals? What is your math background? Do you have any math "blocks"? What general and specific issues and difficulties are arising? What would you like to know about me?
