Math Foundations to Fluency
A comprehensive walk through SAT Math — Algebra, Geometry, Advanced, and Data — sequenced so each pattern unlocks the next. Builds the reflexes high scorers rely on.
Follow this track on your own. Or let JustLockedIn pace it to your test date — and target your weakest patterns first.
It optimizes for the patterns actually costing you points, sequences them around your test date, and layers in timed module practice, Module-2 sets, and full-length tests built exactly like the real Digital SAT® — so the work you do is the work that moves your score.
Solving for the variable in a linear equation
Finding the value of a related expression using a shortcut instead of solving for the variable first
Translating a real-world scenario into a linear equation
Finding slope or intercepts from an equation, often by rearranging into slope-intercept form
Plugging in a value to a linear function to find the output or input
Translating a real-world scenario into an inequality
Applying angle theorems (corresponding, alternate interior, vertical) with parallel lines
Using the Pythagorean theorem or SOHCAHTOA to find a missing side or ratio
Applying 45-45-90 or 30-60-90 side-length ratios to find missing lengths
Identifying center and radius from a circle equation or building the equation
Calculating area, perimeter, or volume using a formula with given dimensions
Rewriting a polynomial as a product of its factors
Applying exponent rules: multiplying, dividing, and handling negative/fractional exponents
Solving quadratic, absolute value, or radical equations
Manipulating a nonlinear function: plugging in values, finding the vertex, or rewriting it
Setting up and solving a proportion to find a missing value
Basic percentage operations: finding the part, percent, or whole
