Digital SAT: Algebra & Advanced Math
Linear equations and systems, quadratics, exponents, polynomials, and function notation — the largest share of the math section.
SAT & ACT math prep
SAT & ACT Math Tutoring — online, one-to-one, at the same $50 rate.
Targeted preparation for the Digital SAT and ACT math sections. We start from where your student is losing points — content gaps, timing, or test mechanics — and work on exactly that. No prepaid packages, no set program length.
$50 / 60 minutes · No contracts · No required packages · No charge for missed sessions
What SAT & ACT math sessions can cover
Digital SAT: Desmos calculator strategy
Using the built-in graphing calculator to solve systems, find intercepts and intersections, and check work quickly.
Problem solving & data analysis
Ratios, rates, percentages, units, and reading tables and graphs — taught by someone with graduate training in statistics and data analytics.
Geometry & trigonometry on the test
Circle equations, angle and triangle relationships, right-triangle trig, and area and volume formulas.
ACT math pacing: 60 questions, 60 minutes
Question triage, when to skip and return, answer elimination, and finishing the harder final third with time left.
ACT content breadth
Quick, targeted review across pre-algebra, algebra, geometry, logarithms, matrices, and trigonometry.
Diagnostic-driven practice
We review a student's practice test or score report and work on the specific question types where points are being lost.
Test-day mechanics
Careful reading of the question, showing work that prevents errors, and steady habits for managing timed sections.
Course work alongside prep
Prep can run beside regular school math so a student never falls behind in class while preparing.
