A shared view of test tags and course sequence
When is this math taught?
Explore where SAT and ACT math topics appear across a typical high school course sequence. Select a curriculum, then a separate Precalculus reference for gaps in that sequence.
Course order and chapter position are curriculum evidence, not a school calendar. Schools may teach topics at different times.
QUESTION-WEIGHTED VIEW
Where the math lands
Each bar is that course’s share of mapped question–topic links in the selected band—not the share of distinct questions. One question can contribute to multiple topics.
CONCEPT CONNECTIONS
Topic families across courses
Line thickness scales with mapped question–topic links. Select a course, a family, or both to narrow the timeline; select again to clear it.
Course and topic-family placements are estimates or references where the selected source lacks a sequence; line weight is not a measure of school adoption.
