Jerry YangI've solved thousands of ACT math problems.
I'm obsessed with this test.
I only tutor one thing: ACT Math, one-on-one. Most of my students find me after a class, a workshop, or another tutor has already covered everything else, because math has more sub-skills than any other section and group prep can't individualize for all of them.

“My ACT math score went up from a 23 to a 30 and I got into Santa Clara University!”
— Rhey Gill, Chaminade High SchoolWhy Just Math?
Because ACT Math has more sub-skills than any other section, and most programs teach it as one generic block.
The specialist, not the generalist
Most of my students find me after a workshop, a class, or another tutoring program has already covered everything else. I'm who they call when math is the one piece still not clicking.
One-on-one, because math isn't one skill
ACT Math tests dozens of distinct sub-skills. A group class teaches to the middle. My diagnostic finds exactly which sub-skills a student is missing, then I teach only those.
Affordable because I only do one thing
Specializing in a single section, one-on-one, is how I can offer truly individualized attention at a rate a full-service program can't match.
Every Skill. Tracked. Checked Off.
My diagnostic doesn't stop at "Geometry" or "Algebra." It tracks 165 named math skills across all 9 ACT categories, verified against 3,060 real problems from 51 official tests. Here's what closing every gap actually looks like.

How I Run the Program
The same five steps I use with every student — whether they're starting fresh or already partway through another program.
Free introductory call
A quick call to talk through what's going on. I get a first read on where the gaps might be, no obligation.
Free diagnostic test
I schedule the student for a full ACT Math diagnostic, broken down by sub-skill, not just a composite score.
Free strategy conference
I grade the diagnostic myself and trace every wrong answer back to the specific concept behind it, then walk you through a personalized, prerequisite-mapped plan — in plain terms, which sub-skills are missing and how many sessions it will realistically take to close them.
Live 1:1 sessions, online
I teach every session myself over Zoom, focused entirely on ACT Math — direct instruction, not a rotating roster.
A recap after every single session
I send parents a written summary of what we covered and what's next, every time.

Results
Real students, real Google reviews.
"If you need help with math, Jerry is your guy."
"Jerry helped me score a 31 on the ACT. He's not only smart, he really knows how to connect with students."
"Oxford definitely saved the day. My tutor Jerry helped improve my ACT score by 7 points!"
"I came to Oxford with a 29 on the ACT and left with a 35. There's no way I could have gotten into Northwestern without their help."
"My tutor motivated me to actually study hard for the ACT — my score jumped 6 points in one test cycle."
"Oxford is without a doubt the best tutoring center. The one-on-one help pushed my score up and gave me the confidence to walk into test day ready."
Akshay Gulabrao, Granada Hills Charter High School
Akshay came to me scoring a 28 on ACT Math — good, but not quite enough to be competitive for the engineering programs he had his sights on. Math was the one section standing between him and those schools, so we diagnosed exactly which sub-skills were costing him points and closed them one by one. He walked away with a 34 in Math, graduated in 2017, and went on to UC Riverside's Computer Engineering program — one of the most competitive majors on campus.
Who I Am
15+ years teaching ACT Math — the person you'd actually work with.
Jerry Yang
I'm a USC Marshall graduate. I can help with any part of the ACT, but math is my passion — it's the subject I love teaching most. I've worked through thousands of ACT Math problems myself, not just to solve them, but to understand exactly how to explain each one clearly. That's what led me to build the prerequisite-chain diagnostic system this practice runs on: math has more sub-skills than any other section, and a generic, one-size class can't individualize for all of them.
