Skype tutoring (math, machine learning, etc.)

I am available to tutor math, computer science, and physics via Skype. I work with both adults (e.g. software developers looking to brush up on math) and younger students, especially students preparing for math competitions.

What I teach

If you are looking for math contest prep, be sure to read the section about that below.

About me

I am friendly, patient, and able to explain things clearly.

I have more than 10 years of tutoring experience and have worked with more than 100 students. I received my SB in Physics from MIT and am an experienced software developer.

I am also very familiar with math contests. I am an instructor at Art of Problem Solving, received honorable mentions on the USAMO and Putnam exams, tied for first place on the Mandelbrot Contest, and was a member of the US Physics Team twice.

See here for my slightly out of date teaching resume.

How Skype lessons work

During lessons I use a tablet device to write on a shared whiteboard. Previously I wrote on paper and made it visible on the camera. Students are welcome to use either method to let me see their work, or they can just talk and I'll do the writing.

For reference, my Skype username is seanmarkan.

Tutoring via email

Occasionally I'm asked about tutoring via email. I am happy to provide advice on math problems via email, and it's the same rate as Skype tutoring, pro-rated to the minute.

Teaching style

I leave it to the student to set the agenda for each lesson. I highly recommend that you bring a set of problems that you are struggling with and want to work through together. This is almost always the most effective way to improve.

Pricing and payment information

The rate is currently $90/hr. You pay only for what you use—if we end a session early I will pro-rate the charge.

You can pay after each lesson or make a deposit in advance (for one or more lessons). I will refund any unused deposit upon request. PayPal, Venmo, and checks are all fine.

How to book a lesson

You can use this convenient online booking tool to see my availability and book immediately, or alternatively feel free to email me at sean.markan@gmail.com.

You should also feel free to use the online booking link if you have an existing appointment and want to reschedule it. There is a box where you can leave me a note to that effect.

Cancellation/no show policy

Please try to provide 12 hours notice if you need to cancel or reschedule. There is no fee to cancel with 12 hours notice. I reserve the right to charge a $20 fee to cancel/reschedule with less than 12 hours notice, and a $40 fee if you don't show up (in which case I will wait 15 minutes for you and then cancel the lesson).

Math contest tutoring

New: You might also be interested in my online problem-solving classes.

I receive a lot of interest from parents who want me to help their children with math contest preparation (for tests like the AMCs and AIME). If you are one of them, please bear the following in mind:

Improving at math contests requires a lot of work and motivation. If your child is not intrinsically motivated to work on them (or if you have to push them), I recommend that you do not choose me as a tutor. It is likely to be frustrating for both of us. However, if your child loves math and wants to learn new things as fast as possible, we're probably a good fit.

On a more concrete level, here are the expectations I have for students working with me on math contests:

If you feel your child can enthusiastically meet these expectations, feel free to get in touch!
