Our SAT Math course provides students with all the content knowledge they need to perform well in the math section of the SAT exam. Filling in missing gaps is the first and most important step towards preparing for the exam as lacking any of these skills will be exposed and reflected in the student's score.

However, to achieve the best possible outcome, students must also dedicate time to a structured and intentional test preparation process, which we describe in this article on how to prepare for a standardized math test.

This course provides everything students need to master the SAT Math curriculum.

Students begin by taking a diagnostic assessment, which will identify their current knowledge frontier and any weaknesses in their foundational knowledge.

Once the student has completed the diagnostic assessment, our sophisticated algorithms will create a custom course that addresses foundational weaknesses along with a plan for building on their existing strengths to attain the highest possible score.

The following data gives the composition of the SAT Math course against the traditional math sequence.

- Prealgebra: 39%
- Algebra I: 39%
- Geometry: 19%
- Algebra II: 3%

For example, 39% of the topics in the SAT Math course are from Prealgebra.
