SAT math, taught one student at a time.
Live 1-on-1 lessons online for students in grades 10–12. Start with a free 25-minute trial lesson and leave with a written plan for the math section.
Then $17/hour. No payment details needed to book.
A question like the ones on the digital SAT
The graph of y = x² − 6x + 5 is shown. What is the minimum value of y?
The lowest point of a parabola is its vertex. Its x-value is halfway between the two places the curve crosses the axis: x = (1 + 5) / 2 = 3.
Put that back in: y = 3² − 6·3 + 5 = 9 − 18 + 5 = −4.
The minimum value of y is −4.
On test day there is a faster way: type the equation into the built-in Desmos calculator and tap the lowest point. We teach both, so you can check one against the other.

Meet for 25 minutes on a video call
We work through a few SAT math questions together to see which topics are solid and which are costing points.

After the call you get an email with what we saw, what to work on first, and how many lessons a week make sense before the test date.

Start weekly 1-on-1 lessons
If the plan suits you, lessons start the same week. If not, you keep the plan and owe nothing.
Who teaches
Lessons are taught by PiSpark's founder, a math teacher who works on one thing: the SAT math section. Every lesson is live and 1-on-1. There are no recorded videos and no group classes.
Each lesson starts from the student's own mistakes. We find the step where a question went wrong, fix the idea behind it, then practice it on new questions until it holds under time pressure.
What it costs
$17 per hour
This is the $17/hour founding-student rate for our first students. Lessons are booked in packs of 8 lessons ($136 per pack).
The trial lesson is free and you are not committed to anything after it.
Questions families ask
+Is this for the digital SAT?
Yes. Lessons follow the current digital SAT math section: algebra, advanced math, problem-solving and data analysis, and geometry and trigonometry. We also teach how to use the built-in Desmos calculator well.
+What do we need for a lesson?
A laptop or tablet with a camera and microphone, a steady internet connection, and paper and pen. Lessons run on a video call with a shared whiteboard.
+We are in a different time zone. Does that work?
Yes. The booking form shows every time in your own time zone, and lesson times are set around US evenings and weekend mornings.
+How does payment work?
There is no payment on this site. After the trial you get an invoice by email for a pack of 8 lessons, payable online.
+What if we need to move a lesson?
Tell us at least 12 hours before and the lesson moves to another time at no cost.
+Do you promise a score?
No, and you should be careful with anyone who does. What we promise is a clear plan, full attention for the whole lesson, and honest feedback on progress.
