The SAT & ACT Reading and Writing Sections: What to Study (and What You Can Skip)

Preparing for the reading and writing portions of the SAT or ACT can feel overwhelming. With timed sections, long passages, and a lot of different question types, many students aren’t sure where to start. The truth is, you don’t need to study everything. Both tests are designed around a predictable set of skills, and focusing on those skills can make studying far more effective. If you’re a high school student preparing for these tests—or a parent helping your student get ready—knowing what to focus on (and what to skip) can make a big difference in both confidence and scores.

One of the most important skills to practice is identifying the main idea of a passage. Many reading questions ask about the author’s purpose or the overall message of the text. Students don’t need to memorize every detail in the passage. Instead, they should focus on understanding what the passage is mostly about. A helpful habit is to pause briefly after each paragraph and summarize it in your own words. This makes it much easier to answer questions about the passage later.

Another skill that appears often is finding evidence in the text. Many questions will ask for the best answer and then ask which sentence supports that answer. These are called evidence-based questions, and they reward students who go back to the passage rather than relying on memory. Encourage students to underline or mentally note important lines as they read so they can quickly find them when answering questions.

Students should also spend time practicing vocabulary in context. Unlike traditional vocabulary tests, the SAT and ACT rarely ask for definitions of difficult words. Instead, they ask how a word is being used within the passage. The best strategy is to reread the surrounding sentences and use context clues to determine the meaning. Substituting answer choices into the sentence can also help students see which one fits naturally.

For the writing and language sections, a strong understanding of basic grammar and sentence structure is essential. Students should review punctuation rules, subject–verb agreement, verb tense consistency, and sentence clarity. These concepts appear frequently on both exams. Practicing short editing exercises can help students quickly recognize and correct these types of errors.

Another area to focus on is clear and concise writing. Many writing questions ask students to choose the best revision of a sentence. Test makers often include answer choices that sound overly wordy or repetitive. In most cases, the best answer is the one that communicates the idea clearly and simply. If two answers say the same thing, the shorter one is often the correct choice.

Finally, students should practice time management. Even strong readers can struggle if they run out of time. Practicing with timed passages helps students learn how long they can spend on each section. If a question is taking too long, it’s usually better to skip it and return later. Developing a pacing strategy can prevent students from feeling rushed at the end of the test.

While there are many skills worth practicing, there are also a few things students don’t need to spend much time on. One common mistake is memorizing large vocabulary lists. Unlike older standardized tests, the SAT and ACT rarely focus on obscure vocabulary words. Students will see much better results by practicing reading passages and using context clues instead of trying to memorize hundreds of definitions.

Another thing students can skip is overanalyzing every detail of a passage. These tests are meant to measure reading comprehension, not deep literary analysis. Students don’t need to break down every sentence or interpret complex symbolism. Instead, they should focus on understanding the general meaning of the passage and locating key information when questions ask for it.

Preparing for the SAT or ACT doesn’t have to mean hours of stressful studying. By focusing on a few core skills—understanding main ideas, finding evidence, using context clues, recognizing grammar patterns, and managing time—students can prepare much more efficiently. When students know what actually matters on the test, they can study smarter, build confidence, and walk into test day ready to do their best.
