ACT Reading: Annotate Passages in 90 Seconds to Boost Accuracy
The Three-Symbol System: Main Idea, Tone, Evidence
Symbol 1: Circle or underline the main idea sentence in each paragraph. This is usually the first or last sentence and summarizes the paragraph's point. Symbol 2: Mark tone shifts with an arrow (↑ for more positive/emphatic, ↓ for more negative/doubtful). Example: A paragraph praises a scientist, but then says "however, her theory was flawed." That "however" marks a tone shift. Symbol 3: Put a star or check mark next to specific evidence (data, examples, quotes) that might support an answer. These three symbols take 30 seconds per paragraph and flag 80% of what questions will ask about.
Why this works: Your brain processes symbols faster than words. When you re-read to answer questions, you spot the circled main idea in one second instead of re-reading the whole paragraph. The annotated passage becomes a visual map of the text.

Mistake 1: Over-annotating. Underlining every sentence or writing notes in the margin turns annotation into re-reading. Stick to three symbols. Mistake 2: Annotating before you know what to look for. Do not annotate the first paragraph until you have read it fully and know what matters. Mistake 3: Using different symbols inconsistently. If a circle means "main idea," use it for every main idea, or your system breaks down. Mistake 4: Annotating the passage before reading questions. This is backwards; skim the questions first (30 seconds), then annotate strategically based on what they ask. The goal is annotation that takes 90 seconds total and cuts your re-reading time from 2 minutes to 30 seconds.
Test this: Time yourself annotating one paragraph with full notes. Then time yourself on another paragraph using only the three symbols. You will see the second method is 3-4x faster.
Practice Annotation on One Short Passage
Take a page from an old ACT reading section. Read the first paragraph. Circle the main idea. Look for tone shifts and mark them. Find one piece of specific evidence and star it. Time yourself; this should take 60-90 seconds for the paragraph, not longer. Repeat for the remaining paragraphs, keeping the pace brisk. Your annotation is complete when you could answer any question by finding the circled main idea and starred evidence without re-reading.
After you finish annotating, answer all five questions for that passage using only your annotations plus a quick re-read of the relevant line. Check your accuracy. If you missed questions, identify whether the annotation failed (you missed the key detail) or whether you misread the question. Adjust your annotation style and try the next passage.

If you annotate efficiently, you spend 6 minutes annotating three passages and 9 minutes answering questions, totaling 15 minutes for three passages. Without annotation, many students spend 8-10 minutes per passage (24-30 minutes total) and still miss questions. Annotation forces you to read strategically, not linearly, which is exactly what the ACT requires.
Starting this week, annotate every reading passage you practice using the three-symbol system. Time yourself and track how your speed and accuracy change. By test day, you will have a battle-tested annotation style that saves you 10+ minutes, giving you time to double-check your hardest questions.
