Since 2005, we’ve helped students improve their confidence and grades in precalculus.

We’re especially proud of the fact that other educators (teachers and professors) and high profile members of the Princeton University Administration trust us with their children’s academic success and recommend our services to others.

We have a 15+ year track record supporting students in Precalculus, Honors & Advanced Precalculus, Calculus, and more.

Our private 1-on-1 precalculus tutors are experts at math and love teaching the subject. They’ve won awards in math competitions and are math majors or have other quantitative majors.

Hi, I’m Dave.

What parents say about our Precalculus tutors

Our team includes award-winning Princeton University undergrads and Master’s/PhD graduates who are rigorously screened and are extremely effective at communicating the material.

A quick “case study”: 

The father of a high school student at West Windsor Plainsboro North contacted us to help his son with precalculus and SAT prep.

We ended up working together for more than three years, and helped the student with his college applications as well

The student’s primary tutor was Dave, a summa cum laude graduate from Princeton University with a major in ecology and evolutionary biology. He was also valedictorian of his high school and captain of his high school tennis team. At Princeton, he played on the JV tennis team and had two scientific papers accepted by well-respected, peer-reviewed journals.

Here’s what our client said after the first year of tutoring:

“Dave was a class act through the year… Richard did struggle but Dave was terrific through the process and served as not just a very good tutor but a terrific role model for Richard.”

And, three years later:

“Just a quick FYI that Richard did end up getting into his first-choice program…dual major in public communications and information technology at Syracuse.

Was a bit of a reach for him given it is top-rated program for both but the combination of surge over the years + strong extracurriculars got him there 😉

You guys have obviously been very helpful over the years so wanted to pass this along.

Dave in addition to general tutoring was very helpful with the common app essay review process. Look forward to starting up with Richards’s brother!”

We receive messages like these every week.

We regularly track progress

Progress reports are shared after every session so you always know what’s going on.

A Real-Life Example: 

Student: Aliza
Tutor: Zachary
Subject(s): Precalculus
Date: 10/07/2019
Time Tutored: 16:15 – 17:15
Next Scheduled Session: Mon, 10/14 4:15 PM

Material Covered:

First we looked at solving for trig functions given a statement such as “cos x = 5/7”. We discussed how to draw a picture using the given information and the fact that tangent is only positive in the first and third quadrants.

We then went over finding reference angles. The key for reference angles is to know what quadrant you are in, and then solve the right formula. For example, in the second quadrant, the reference angle and the given angle sum to 180 degrees. These questions are often simplified by subtracting 2 pi radians (or 180 degrees) from the given angle or by switching from negative to positive.

We then solved a few calculations of trig functions. Lastly, we went over two word problems from the textbook. For those, it is often helpful to draw a picture to verify what trig function you want to use. Think about what side of the right triangle you are given and then use the corresponding trig function.

Additional Comments:

It was great meeting you and Aliza! I think today’s session went really well. Aliza was very engaged and prepared to work. I can tell that she understands the material well, but she needed some help understanding a few of the different kinds of problems that are presented.

In precalculus, the problems have a lot of variety, and that can make it tricky to remember everything. I think Aliza has a better grasp now of how to solve these different problems, especially solving for reference angles.

If you have any comments, questions, or concerns, please let me know. I would love to hear feedback and work with you to make every session as productive and helpful for Aliza as possible. Feel free to text, call, or email me any time.

Assignments for Next Week:

For the quiz tomorrow, be sure to know how to fill out the unit circle. Make sure you understand how to solve reference angle problems. For word problems, drawing a picture and then using the correct trig function is key. Think about how we went about solving the first word problem.

Good luck on the quiz! I think you have a good understanding of the material. Be sure to check your results to see if they make sense and show your work! You got this!

How is your child performing in Precalculus?


Addresses common student issues

A deep understanding of the subject matter allows us to personalize our approach.

Why is Precalculus important?

Pre-calculus, as the name suggests, prepares students for calculus.

The topics covered in pre-calculus can vary between regular and honors or college-prep levels, but generally advance upon the topics learned in Algebra 2 and trigonometry.

Why do some students struggle with Precalculus?

Doing well in precalculus requires a good foundation in algebra, algebra 2, and trigonometry.

Gaps in foundational math will cause some problems. Students will also be introduced to more advanced topics. Some classes might focus more on conic sections, vectors and other topics covered in calculus.
