What we cover
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, with practice interpreting quantitative information.
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 to support both current coursework and test preparation.

Family cancellation policy, effective November 1, 2026
Cancel or reschedule with at least 12 hours' notice without charge. With less notice, the full $50 session fee may be charged. Student no-shows are generally charged the full scheduled fee. If Northstar cancels, you are not charged; any payment collected for that session is refunded or credited as appropriate. Rescheduling depends on mutual availability. Previously agreed individual exceptions are honored, and this policy does not apply to earlier sessions.
Private tutoring is $50 per 60-minute session. Invoices are typically issued after 4 tutoring sessions and paid through Zelle. Late-cancellation or no-show fees may appear on an invoice. No required prepaid packages or long-term commitments.
