Reasoning Through Language Arts

占考试 27%
学习 →
Locate the main idea
Ask what single point most of the sentences support; it is often stated near the beginning or end of a paragraph.
Separate details from the main idea
Details are specific facts or examples that explain or prove the main idea, not the main idea itself.
Summarize in your own words
Restating a passage briefly in your own words confirms you understand its central message.
Watch for topic sentences
A topic sentence often signals the paragraph's main idea and guides how the rest of the paragraph develops.
Base inferences on evidence
A good inference is supported by specific words or details in the passage, not personal assumptions.
Ask what is implied
Look for what the author suggests through tone, word choice, and context clues rather than direct statements.
Cite supporting text
When a question asks for evidence, point to the exact sentence or phrase that backs the conclusion.
Avoid overreaching
Reject answer choices that go beyond what the text can reasonably support.
Use context clues
Nearby words, definitions, and examples often reveal the meaning of an unfamiliar word.
Watch for contrast signals
Words like 'but' or 'however' can show that a term means the opposite of what came before.
Consider connotation
Decide whether a word suggests a positive, negative, or neutral feeling to grasp the author's tone.
Substitute a synonym
Replacing the word with a possible synonym and rereading the sentence tests whether your meaning fits.
Subject-verb agreement
A singular subject takes a singular verb and a plural subject takes a plural verb, even when words separate them.
Correct pronoun reference
Every pronoun must clearly and correctly refer to a specific noun and agree with it in number.
Fix run-ons and fragments
Join or separate clauses properly so each sentence expresses a complete thought with correct punctuation.
Punctuate correctly
Use commas, semicolons, and apostrophes according to standard rules, such as commas after introductory clauses.
Keep verb tense consistent
Avoid shifting between past, present, and future tense unless the meaning requires it.
State a clear thesis
Begin with a sentence that states your main claim so the reader knows your position.
Use transitions
Words like 'first,' 'however,' and 'therefore' show how ideas connect and improve flow.
Support with evidence
Back each point with specific details or quotations drawn from the passage.
Plan before writing
A brief outline of your main points helps keep the essay organized and on topic.
Review and edit
Leave time to check for grammar, spelling, and clarity errors before finishing.

Mathematical Reasoning

占考试 28%
学习 →
Follow the order of operations
Work through parentheses, exponents, multiplication and division, then addition and subtraction, in that order.
Operate with fractions
Find common denominators to add or subtract fractions, and simplify results to lowest terms.
Handle negative numbers
Adding a negative moves left on the number line, and subtracting a negative is the same as adding a positive.
Convert between forms
Fractions, decimals, and percents represent the same values and can be converted from one to another.
Set up proportions
Write two equal ratios and cross-multiply to solve for an unknown quantity.
Find the unit rate
Divide to find the cost or amount per single unit, then scale up to any quantity.
Calculate percents
Convert a percent to a decimal and multiply to find a percentage of a number.
Compute percent change
Divide the amount of increase or decrease by the original value, then multiply by 100.
Isolate the variable
Use inverse operations on both sides of an equation to get the variable by itself.
Use the distributive property
Multiply a factor outside parentheses by each term inside, as in 4(2x + 3) = 8x + 12.
Solve inequalities carefully
Treat inequalities like equations, but reverse the sign when multiplying or dividing by a negative number.
Translate words to symbols
Turn phrases like 'a fixed fee plus a rate per item' into expressions such as 30 + 0.10t.
Check your solution
Substitute your answer back into the original equation to confirm it makes the statement true.
Know key area formulas
Rectangle area is length times width, and triangle area is one-half base times height.
Work with circles
Circumference equals 2 times pi times the radius, and area equals pi times the radius squared.
Apply angle rules
The angles of a triangle add to 180 degrees, and complementary angles add to 90 degrees.
Track your units
Express area in square units and volume in cubic units to keep measurements meaningful.
Calculate the mean
Add all values in a set and divide by the number of values to find the average.
Find the median
Order the values and identify the middle one; with an even count, average the two middle values.
Compute probability
Divide the number of favorable outcomes by the total number of possible outcomes.
Read graphs carefully
Check titles, labels, and scales before drawing conclusions from a chart or graph.

Science

占考试 23%
学习 →
Cells are the basic unit of life
All living things are made of cells, which carry out the processes needed for life.
Energy flows through food chains
Producers make food from sunlight, and consumers and decomposers pass energy through the ecosystem.
Traits are inherited through genes
Offspring receive genetic instructions from parents that determine inherited characteristics.
Evolution changes species over time
Populations change across generations through processes such as natural selection.
Distinguish physical and chemical changes
Physical changes alter form without creating new substances, while chemical changes produce new substances.
Understand properties of matter
Physical properties like density can be measured without changing a substance's identity.
Recognize forms of energy
Energy takes forms such as chemical, kinetic, thermal, and light, and can change from one to another.
Apply forces and motion
Forces like gravity and friction affect how objects move or stay at rest.
Trace the water cycle
Water moves through evaporation, condensation, precipitation, and collection in a continuous cycle.
Distinguish weather and climate
Weather is short-term and local, while climate describes long-term patterns over many years.
Classify natural resources
Renewable resources like sunlight are replenished, while fossil fuels can be used up.
Know the solar system
Planets orbit the Sun, and their distance affects temperature and orbital period.
Identify variables
The independent variable is what you change, and the dependent variable is what you measure in response.
Use controls
A controlled experiment changes only one variable at a time so results can be attributed to that factor.
Value repetition
Repeating trials and getting similar results makes conclusions more reliable and trustworthy.
Draw evidence-based conclusions
Base conclusions on the data provided rather than on assumptions or opinions.
Read every label
Check the title, axis labels, and units before interpreting a graph or table.
Identify trends
Look for patterns such as steady increases or decreases across the data.
Compare data points
Use the values shown to compare quantities and support or reject a claim.
Make predictions
Extend an observed trend cautiously to estimate values beyond the given data.

Social Studies

Know the three branches
The legislative branch makes laws, the executive enforces them, and the judicial interprets them.
Understand separation of powers
Dividing authority among branches with checks and balances prevents any one from dominating.
Recognize constitutional rights
The Bill of Rights protects freedoms such as speech, religion, and a fair trial.
Identify citizen duties
Responsibilities include voting, obeying laws, and serving on a jury when called.
The founding documents
The Declaration of Independence explained separation from Britain, and the Constitution framed the government.
Causes of the Civil War
Slavery and disputes over states' rights led to the conflict that ended slavery through the Thirteenth Amendment.
Industrial and economic change
Inventions like the steam engine shifted the economy toward factories and mass production.
The struggle for equal rights
The Civil Rights Movement sought to end segregation and secure equal rights for African Americans.
Understand supply and demand
When demand rises and supply stays the same, prices tend to increase.
Define inflation
Inflation is a general rise in prices that reduces the purchasing power of money.
Compare economic systems
Capitalism relies on private ownership and markets, unlike systems with heavy state control.
Recognize trade terms
Exports are goods sold abroad, imports are goods bought from abroad, and tariffs tax imports.
Read map types
Political maps show borders between countries and states, while physical maps show natural features.
Use map scale
A map scale relates distance on the map to actual distance on the ground.
Interpret map symbols
A legend explains what colors, lines, and symbols on a map represent.
Link geography to human life
Landforms, climate, and resources influence where people settle and how they earn a living.
Distinguish source types
Primary sources are firsthand accounts, while secondary sources analyze events after the fact.
Interpret visual data
Read charts, graphs, and maps carefully, noting labels and scales before concluding.
Detect point of view
Consider an author's perspective and possible bias when evaluating a source.
Support claims with evidence
Back conclusions with specific details drawn from the documents or data provided.
