Algebraic Concepts
Solve one-variable linear equations including those with variables on both sides and parentheses
Solve and graph one-variable linear inequalities, flipping the inequality when multiplying or dividing by a negative
Rearrange formulas to isolate a specified variable
Set up and solve linear equations from real-world contexts
Your checkpoint
A timed 15-question equation-and-inequality quiz completed in 30 minutes with at least 12 correct
Algebraic Concepts
Identify slope and intercepts from equations, tables, and graphs of lines
Write the equation of a line given two points or a point and a slope
Graph linear equations and inequalities on a coordinate plane
Interpret slope and intercept in context (rate of change, starting value)
Your checkpoint
A graphing portfolio of 8 lines and 2 inequalities, each with its equation, slope, intercepts, and a one-sentence real-world interpretation
Measurement/Geometry
Convert units within and across measurement systems using dimensional analysis
Compute perimeter, area, and volume of common two- and three-dimensional figures
Apply the Pythagorean theorem to find missing side lengths
Classify angles, triangles, and polygons and use angle-sum properties to find unknown angles
Your checkpoint
A formula reference card (all perimeter, area, volume, and Pythagorean formulas) plus 12 solved applied geometry problems showing unit labels at every step
Measurement/Geometry & Data Analysis/Probability/Statistics
Solve problems involving similar figures and scale drawings using proportions
Compute mean, median, mode, and range from a data set and describe how outliers affect them
Read and interpret bar graphs, line graphs, circle graphs, and scatter plots to answer comparison questions
Calculate simple probabilities from tables and frequency counts
Your checkpoint
A 10-question data-and-geometry mixed quiz scoring 80% or better, with a written explanation of any graph-interpretation errors
Data Analysis/Probability/Statistics
Distinguish correlation from causation when reading scatter plots and trend lines
Compute and interpret probabilities of simple and compound events
Evaluate sampling and data-collection descriptions for bias and representativeness
Choose the appropriate measure of center or spread for a given data context
Your checkpoint
A one-page written analysis of a self-collected or invented data set (at least 15 values) reporting center, spread, a graph, and one probability statement
Numbers and Operations on Numbers & Measurement/Geometry & Data Analysis/Probability/Statistics & Algebraic Concepts
Complete two full-length timed practice tests under exam conditions
Categorize every missed item by domain and error type (concept, computation, misread)
Re-solve every missed item correctly without notes
Build a one-page personal error-pattern checklist for test day
Your checkpoint
A completed error-analysis log for both practice tests with a target of 75% or higher on the second attempt and zero unresolved items
