MCAT master learning domain map
Independent test-preparation practice
A complete content inventory of MCAT material, reorganized into teachable domains so tutors can sequence prerequisites, practice and mastery checks.
- 24
- Instructional domains
- From quantitative foundations to novel problem solving
- 5
- Detailed domain documents
- Math, physics, general and organic chemistry, biochemistry
- 1
- Sequencing index
- Used for planning and progress tracking
Context
Students preparing for the MCAT usually work from resource lists rather than a curriculum. Tutors were assembling study plans from memory, so coverage varied between students and weak prerequisites were often discovered late in the preparation period.
Question
What would it take to plan MCAT preparation as a curriculum instead of a reading list?
Approach
- Inventoried the tested content in full, then regrouped it into instructional domains rather than the official concept headings
- Split quantitative foundations out as their own domain, because weak arithmetic and algebra block progress in physics, chemistry and data interpretation
- Broke every domain into sub-domains and individual topics small enough to teach, practise and check
- Marked dependencies so prerequisite topics are scheduled before the topics that rely on them
- Kept reasoning and research-methods skills as separate domains rather than folding them into science content
- Wrote the map so a tutor, a study group or a student working alone can all use it
Deliverables
- Master domain map covering 24 instructional domains
- Separate working documents for the quantitative, physics, general chemistry, organic chemistry and biochemistry domains
- Sub-domain breakdowns with an explicit topic list under each
- A master domain index for sequencing and progress tracking
- Guidance for turning the inventory into a dated study plan
Sample material
One domain from the map, reproduced as it appears in the inventory. Every domain is broken into sub-domains and then into individually teachable topics.
Domain 1 — Mathematical and quantitative foundations
- Position
- Scheduled first; prerequisite to Domains 2–5
- Sub-domains
- Five
- Use
- Diagnostic, sequencing and mastery checklist
1A. Arithmetic
- Fractions, decimals, percentages, ratios, proportions and rates
- Scientific notation, orders of magnitude and estimation
- Significant figures, unit conversion and dimensional analysis
1B. Algebra
- Solving and rearranging equations; systems of equations; inequalities
- Exponents, roots and exponential relationships
- Logarithms, natural logarithms and manipulation of scientific formulas
1C. Functions and graphs
- Independent and dependent variables; slope and intercepts
- Direct, inverse, quadratic, exponential and logarithmic relationships
- Interpreting graphs, interpolation, extrapolation and area under a curve
1E. Probability and statistics
- Mean, median, mode, range, variance and standard deviation
- Distributions, percentiles, statistical significance and confidence intervals
- Correlation, regression, sampling, bias, error, precision and accuracy
Topics in this domain are checked before physics and general chemistry are scheduled, because they appear inside almost every calculation in those domains.
Use
A tutor diagnoses which domains are secure, schedules the unsecured ones in dependency order, and uses the topic lists as the checklist for practice and mastery review. Students can see exactly what remains.
Reflection
Most preparation plans fail on sequence, not on content. Separating quantitative foundations into their own domain surfaces the gaps that quietly slow everything else down.
This example is illustrative. The organization, data and findings are fictional and are used to show the structure and level of analysis of a Common Thread engagement.
