Domain & Question-Type Map
The whole test on one page — what's tested, how much, and which module fixes it
3 min read
Know the weightings and you know where your points live: ~70% of Math is Algebra + Advanced Math, and ~54% of R&W is Craft & Structure + Information & Ideas. This map is the at-a-glance index of every domain, question type, and the MERIDIAN module that trains it.
Sources (official weightings): College Board Test Specifications Overview + math/R&W pages. Per-skill counts are prep-community estimates (not official) — directional only. Canonical names + verbatim official domain descriptions: SIGNAL · Official Taxonomy Map (grounded in Assessment Framework v3.01, Tables 10/16).
STRUCTURE
Reading & Writing : 2 modules × 27 Q × 32 min = 54 Q / 64 min
Math : 2 modules × 22 Q × 35 min = 44 Q / 70 min
Total: 98 Q · 2 h 14 min · one 10-min break · ~2 unscored pretest items per module
Adaptive: Module 1 → easier/harder Module 2 (independent per section)
READING & WRITING — domains, weights, types → module
Questions appear grouped by domain in this fixed order, easy→hard within groups.
| Domain | Weight | Question types | MERIDIAN module |
|---|---|---|---|
| Craft & Structure | ≈28% | Words in Context · Text Structure & Purpose · Cross-Text Connections | Words-in-Context System · Craft & Structure + Cross-Text |
| Information & Ideas | ≈26% | Central Ideas & Details · Command of Evidence (Textual) · Command of Evidence (Quantitative) · Inferences | Command of Evidence (T+Q) · Inferences System · Craft & Structure + Cross-Text |
| Standard English Conventions | ≈26% | Boundaries · Form, Structure & Sense | CODEX · Grammar Ruleset Vault |
| Expression of Ideas | ≈20% | Transitions · Rhetorical Synthesis | Transitions + Rhetorical Synthesis |
Words in Context is the single most frequent type; Inferences the hardest.
MATH — domains, weights, types → module
| Domain | Weight | Skill points | MERIDIAN module |
|---|---|---|---|
| Algebra | ≈35% | linear equations (1 & 2 var) · linear functions · systems · linear inequalities | Algebra System |
| Advanced Math | ≈35% | equivalent expressions · quadratics · exponentials · polynomials/rational/radical/absolute value · nonlinear systems · functions | Advanced Math System |
| Problem-Solving & Data | ≈15% | ratios/rates/proportions/units · percentages · one- & two-variable data · probability & conditional · sample inference & margin of error · study design | Problem-Solving & Data System |
| Geometry & Trig | ≈15% | area/volume · lines/angles/triangles · right-triangle trig · circles (equation, arc, sector, radians) | Geometry & Trig System |
~75% multiple choice · ~25% grid-in (SPR). Desmos on every question. Reference sheet = geometry-only.
WHERE YOUR POINTS LIVE (prioritisation)
- Math: Algebra + Advanced Math = ~70% and most of the hard Module 2 → highest priority for content completeness + Desmos.
- R&W: Craft & Structure + Information & Ideas = ~54% → the reading types; Conventions (~26%) is the fastest-to-master block (rule-based).
- Your weak side (R&W): lead with the Grammar Vault (rule-based, fast) + Words-in-Context (most frequent) + Inferences (hardest), then the rest.
REFERENCE CARD — DOMAIN MAP
R&W 54Q/64m: Craft&Structure 28% · Info&Ideas 26% · Conventions 26% · Expression 20%
MATH 44Q/70m: Algebra 35% · Advanced 35% · Problem-Solving&Data 15% · Geometry&Trig 15%
~70% of Math = Algebra+Advanced. Conventions = fastest R&W points. Words-in-Context = most frequent.
