Reading a passage once and then answering comprehension items from memory, without returning to the specific sentences each question depends on.
The ELA section is timed and passages feel familiar after one read, so candidates trust a general impression of the author's point instead of verifying the exact wording an inference or vocabulary-in-context item hinges on.
What to do instead
For every item, locate and re-read the one to three sentences that contain the answer or its evidence before choosing. Practice by covering the choices, predicting the answer from the text, then matching. Time yourself so re-reading stays inside roughly 60-75 seconds per item.
Choosing a grammatically correct rewrite of a sentence that changes the author's original meaning, or picking the version that sounds most formal rather than the one that preserves sense and fixes the actual error.
Usage and sentence-correction items offer distractors that are fluent and polished; candidates equate sophistication with correctness and stop checking whether the original claim survived intact.
What to do instead
Apply a two-part test in order: does the revision fix the identified error, and does it keep the original meaning? Eliminate any choice that adds, drops, or reverses information. Drill with paired sentences where the grammatically fine option is semantically wrong.
Treating a multi-step word problem as a single operation, grabbing the two most visible numbers and computing with them without writing down what is being asked.
Under time pressure, keyword matching ('total' means add, 'left' means subtract) replaces modeling, and problems with rates, unit conversions, or an intermediate quantity get collapsed into one step.
What to do instead
Before computing, write one sentence naming the unknown and list the given quantities with units. Then sketch the chain of operations needed to get from givens to unknown. Practice problems that deliberately include an unused number so keyword matching fails.
Estimating or eyeballing geometry and data questions (areas, angles, slopes, chart values) instead of setting up the formula or reading the axis labels and scale.
Diagrams are drawn roughly to scale and answer choices are spaced so a plausible guess looks right; candidates skip checking units, axis increments, or whether a figure is labeled 'not to scale'.
What to do instead
State the formula or the quantity being read from the graph before looking at the choices, and check the axis labels and increments explicitly. For geometry, redraw or annotate the figure with the given values. Verify by a second method (estimation) only after computing.
Misreading the question stem's qualifier, answering 'which is NOT' or 'which best' as if it asked for the true statement or the only true statement.
Stems are short and the brain fills in the more common positive phrasing; negative and superlative qualifiers are easy to skip when moving fast.
What to do instead
Circle or mentally flag every negation and superlative in the stem before reading choices, and restate the task in your own words ('find the false one'). On review passes, re-read the stem first, not the choices.
Answering social studies items from general impressions of an era or event rather than from the specific document, date, or causal relationship the item tests.
Broad narrative familiarity ('the Civil War was about slavery and states' rights') feels like knowledge, but items often test chronology, primary-source point of view, or the difference between a cause and a consequence.
What to do instead
Build a one-page timeline of major eras and turning points and practice placing events on it. For any document or quote, identify author, audience, and date before interpreting. Practice distinguishing 'cause', 'effect', and 'context' in the same event.
Confusing similar-but-distinct civics and economics terms, such as federalism versus separation of powers, or supply shift versus movement along the supply curve.
The terms are introduced together and share vocabulary; recognition memory says 'I've seen that' without discriminating between the concepts, and distractors are built from exactly these near-misses.
What to do instead
Make a two-column contrast sheet for each confusable pair with a one-line definition and a concrete example, then self-quiz by writing the definition from the term. For economics, draw the graph and label which curve moves versus which point moves.
Applying a remembered science fact or formula without checking whether the conditions of the problem match, for example using a gas law outside constant temperature or ignoring significant figures and units.
Science items in a general exam reward recall, so candidates pattern-match to a familiar law and skip the assumptions (constant pressure, ideal behavior, conservation) that make it valid.
What to do instead
Before calculating, list the knowns with units and write the conditions or assumptions the law requires. Convert to consistent SI units first. After computing, sanity-check magnitude and units, and confirm the answer's precision matches the given data.
Treating experimental-design and data-interpretation items as reading comprehension, picking the choice that restates the passage rather than identifying the variable, control, or flaw the item asks about.
These items are wordy and look like reading questions; candidates miss that the task is to distinguish independent from dependent variables, find the control group, or judge whether a conclusion follows from the data.
What to do instead
For each experiment described, label the independent variable, dependent variable, and controlled conditions in the margin. Ask whether the conclusion is supported by the data shown or merely consistent with it, and eliminate choices that overstate the result.
Spending disproportionate time on a few hard items in one domain and rushing or guessing on later items, without using the flag-and-return strategy across the four sections.
The exam spans four domains in one sitting and candidates treat it as a single continuous test, so a stubborn math problem drains minutes that belong to easier science or ELA items later.
What to do instead
Adopt a per-item time cap (roughly 60-75 seconds), flag anything exceeding it, and move on; return only after finishing the section. Take at least two full-length timed practice runs to calibrate pacing and to rehearse the flag-and-return habit under realistic conditions.
