Math tutoring · Grades 6–12 · One-on-one
Online math tutor, from pre-algebra to AP Calculus.
In math, an idea missed in September becomes a lost grade in March. As an online math tutor, Rijul teaches middle and high school students one-on-one, finds the step that went missing, rebuilds it, and then keeps your student a step ahead of the class.
Taught by Rijul, a UC Berkeley Regents’ Scholar
Dual degree in Data Science and Business Administration
Teaches middle school math through AP Calculus, SAT and ACT
Courses
Find your student’s course.
Middle school math
Grades 6–8 and pre-algebra
Fractions, ratios, negative numbers and first equations: the ground every later course stands on.
Algebra 1
Usually 8th or 9th grade
Equations, slope, functions, systems and quadratics, taught until the steps make sense.
Geometry
Usually 9th or 10th grade
Proofs, congruence and similarity, right-triangle trigonometry, circles and volume.
Algebra 2
Including Honors and Trig
Functions in depth, polynomials, logarithms and the first full look at trigonometry.
Precalculus
Including AP Precalculus
Every major function family, trigonometric identities and polar coordinates, ready for calculus.
AP Calculus
AB and BC
Limits, derivatives, integrals and series, with free-response practice for the exam in May.
Who it’s for
Four reasons families get in touch.
Falling behind
A test grade drops and no one is sure why. Usually it traces back to one skill from an earlier unit that never fully settled.
Holding an honors grade
Honors and accelerated courses move quickly. Steady sessions keep a strong student from being caught out by one hard unit.
Getting ahead
A summer or a quiet stretch is the time to preview next year’s course, so the fall’s first units feel familiar instead of new.
A big exam coming
A final, an AP exam or the math on the SAT or ACT. The plan works back from the date.
Math is half the score on the SAT and one of the three sections behind the ACT composite. For test preparation, see SAT prep and ACT prep.
The approach
How math is taught here.
Find where it started
A mistake in a new topic often has an older cause: fraction arithmetic inside a rational equation, or algebra inside a calculus problem. Sessions trace the error back to its source.
Understand, then practice
Each idea is worked through at the board until your student can say why each step works. The practice that follows is written for them and checks that understanding.
Work from the real course
Sessions work from the school’s own syllabus, textbook and homework, so the work done with Rijul is the work that gets graded.
How it works
Every course starts the same way.
Open slots: weekdays after school, until 8 p.m. Eastern Time, and weekends.
- 01
A free consultation
We talk about the course, the most recent tests and what your student says is hard. A recent quiz or test is a useful thing to have on hand.
- 02
A skills check
A brief diagnostic of the topics the current course depends on, so the plan starts from what your student actually knows.
- 03
A written plan
What to repair, what to preview and when, set against the school’s calendar and the dates of big tests.
- 04
One-on-one sessions
Live over Zoom: the idea at the board, then problems chosen for your student and pitched at the level of the class.
- 05
Updates for parents
A note to you at regular intervals on what was covered, what is improving and what comes next.
Your tutor
Who teaches: Rijul.
Every math student at Vidansa works with Rijul, the founder. He holds a dual degree in Data Science and Business Administration from UC Berkeley, where he was a Regents’ Scholar.
Before Vidansa, he spent his Berkeley summers in analytical roles at Houlihan Lokey and Summit Partners, then joined a leading North American educational consulting firm. Whatever the course, the order of a lesson is the same: understand it at the board, then practice it on problems written for the student.
Testimonials
What families say.
“My two kids, now 7th and 5th grades, have been working with Rijul for 2.5 years, and both started well behind grade level. Both my kids wrapped up the previous school year top of their classes. My son was invited to compete in a global math competition as a representative of the school for this current school term. Math has become their favorite subject, they look forward to new concepts and challenges, and tackle them with true confidence.

“Rijul not only teaches them math, but also instills a genuine curiosity and joy for learning. My kids love their tutoring sessions, and actively ask for extra time with Rijul if they have an exam to prep for.
“Rijul truly cares about his students. We started working together in CA, then relocated to Hong Kong. Despite the time difference, Rijul has made sure my kids do not skip a beat in math. My son also often praises that Rijul teaches in ways he can actually understand.
“We are so deeply grateful for all the work Rijul has done.”
TS · Parent of 5th and 7th graders, Hong Kong “Rijul has been an incredible math and science tutor for my daughter. Beyond helping her strengthen her understanding of the subjects, he has helped her become more diligent, confident, and accountable as a student. What really sets Rijul apart is how invested he is in her success — he checks in regularly, follows up on her progress, and genuinely cares about her outcomes. We have seen a meaningful difference in both her confidence and her approach to school since working with him.”

Questions
Math tutoring questions.
How much does math tutoring cost?
$150 per hour for one-on-one math tutoring, whatever the course, and there’s no charge for the first consultation call.
Which math courses do you teach?
Middle school math and pre-algebra, Algebra 1, Geometry, Algebra 2 and trigonometry, Precalculus and AP Precalculus, and AP Calculus AB and BC, including honors sections.
Do you help with homework?
Sessions often use the week’s assignments as material, but the aim is understanding, so that the next assignment can be done without help.
How do online math sessions work?
Sessions happen on Zoom, and your student and Rijul write on the same digital whiteboard, so he sees every step of the work as it happens, not just the final answer.
We’re not on Eastern Time. Will scheduling work?
Families anywhere in the US are welcome. Open slots run on weekdays after school until 8 p.m. Eastern Time, which is 5 p.m. Pacific, and on weekends.
