SAT Reading and Writing: a skill-by-skill guide

01The four domains and ten skills

The domain names organize your review. Within a domain, label the skill and the actual decision that caused the miss.

02Evidence and inference: keep the claim narrow

Suppose a passage says a plant grew taller in shaded plots than in sunny plots during one experiment. “Shade increased height in those plots” stays within the finding. “All plants need shade to thrive” adds a population and outcome the experiment did not establish.

For a graph, identify the axis units and comparison before reading the choices. An answer can mention the right variables and still reverse their relationship. Write the evidence in a short phrase, then check whether every part of the answer follows.

For a central idea, cover the whole passage without adding a recommendation the author never makes. For an inference, choose the conclusion supported by the given information; a plausible fact from outside the passage is not enough.

03Vocabulary and author choices

In Words in Context, replace the blank with a rough word before reading the options. If a result contradicts an earlier theory, a word meaning “challenges” can fit; one meaning “confirms” cannot, even if both sound academic.

For structure and purpose, name what a sentence does: introduce a hypothesis, give evidence, acknowledge a limit, or contrast an interpretation. Summarizing what the sentence says does not necessarily explain its function.

For paired texts, identify each author’s claim independently. An answer about agreement must match both positions, not just use a phrase familiar from one text.

04Transitions: identify the relationship first

“The prototype was inexpensive. ___, it broke after a week.” The second sentence introduces a drawback, so a contrast transition fits. “Therefore” would claim that being inexpensive caused the failure, which the text did not establish.

Reduce the sentences to two short ideas, name the relation, and then test the transition. Words such as “moreover,” “however,” and “therefore” are not interchangeable decorations.

05Boundaries: test the clauses

“The sample was small; the result needs replication.” Both sides can stand as sentences, so a semicolon can join them. A comma alone would create a comma splice.

A colon needs a complete clause before it and an explanation or elaboration afterward. In “The team identified one limitation: the short observation period,” the words before the colon already make a complete statement.

For agreement, locate the subject rather than the nearest noun. In “The collection of samples is frozen,” collection is singular even though samples is plural. For a modifier, ask which noun the opening phrase actually describes.

06Rhetorical synthesis: obey the stated goal

If the notes include a researcher’s name, two discoveries, and a date, an answer can be factually accurate and still fail a goal asking you to compare the discoveries. Read the goal before sorting the notes.

For a goal to emphasize a similarity, choose a sentence that names the shared property. For a goal to introduce a researcher to an unfamiliar audience, include identifying context. Do not reward an answer merely for using the greatest number of notes.

07Practice accuracy and pacing together

Thirty-two minutes for 27 presented questions averages about 71 seconds each. Allocate time according to the item, and mark a best attempt before moving on when a passage is consuming the module.

I would review an error by identifying the exact unsupported phrase or rule, rather than writing “read more carefully.” For example: “I chose an answer about all species, but the study measured one species.” Then try an unseen question from the same skill.

Alternate a small focused set with a full timed module. A correct answer after reading the explanation is useful for learning, but a fresh question is the better check of whether you can apply the rule independently.
