Last Updated: April 8, 2026
The ACT is one of the most important tests you will take in high school, and the good news is that it is very learnable. With the right plan, consistent practice, and smart strategies, most students can raise their composite score by 4 to 8 points in just a few months. This guide walks you through every step of how to prep for the ACT, from your first practice test to test day.
Whether you are starting from scratch or looking to push past a plateau, this is the comprehensive strategy guide that covers it all: the 2026 format, section-by-section breakdowns, study timelines, resources, and the mistakes to avoid along the way.
What the ACT Looks Like in 2026
Before you start studying, you need to understand exactly what you are preparing for. The ACT changed significantly in 2025, and the 2026 format reflects those updates.
The biggest change: Science is now optional and no longer counts toward your composite score. Your composite is the average of English, Math, and Reading only. Science is still scored 1 to 36 and reported when you take it, and some schools (Georgetown, Boston University, the service academies) still require it. Read our ACT Science strategy guide to decide whether to take it.
The ACT is available on paper or digitally. The content is identical on both, but the digital version includes a built-in Desmos calculator for the entire Math section, which is a meaningful advantage.
Step 1: Take a Diagnostic Test and Set Your Goal
You cannot build a prep plan without knowing where you stand. Start by taking a full-length, timed ACT practice test under realistic conditions. No phone, no breaks between sections (except the scheduled ones), and strict time limits.
Your diagnostic score tells you two things:
- Your starting composite, which becomes the baseline you measure all progress against
- Your section breakdown, which reveals where the biggest point gains are hiding
Next, set a target score. Look up the middle 50% score range for admitted students at your target schools. Here is a rough guide:
A realistic improvement target for most students is 4 to 6 points with 2 to 3 months of consistent prep. If you need a bigger jump, plan for 4 to 6 months. Take a free diagnostic quiz on Larry Learns to get your starting score today.
Step 2: Build Your Study Plan
The best ACT prep plans are structured around your weakest sections, not equal time across all four. Here is how to allocate your time based on your diagnostic results.
The 60/30/10 Rule
- 60% of your study time goes to your weakest section (the one with the biggest gap between your current score and your target)
- 30% of your study time goes to your second-weakest section
- 10% of your study time goes to maintaining your strongest section with occasional practice
For example, if your diagnostic comes back English 28, Math 22, Reading 25, your Math gets the most attention because that is where you can gain the most points.

Step 3: Learn Each Section Inside and Out
Each ACT section tests different skills and rewards different strategies. Here is your section-by-section breakdown with links to our detailed guides.
ACT English: Grammar Rules and Rhetorical Strategy
The English section gives you 75 questions in 45 minutes across 5 passages. That is 36 seconds per question, making it the fastest-paced section. About 53% of questions test grammar and usage (commas, subject-verb agreement, pronoun clarity), and 47% test rhetorical skills (organization, style, strategy).
Key strategies:
- Memorize the core grammar rules. There are roughly 15 to 20 rules that cover the vast majority of grammar questions. The ACT recycles these patterns constantly.
- When in doubt, the shortest answer is often correct. The ACT penalizes wordiness and redundancy.
- For rhetorical questions, always consider the context of the full paragraph, not just the underlined portion.
- Read the question stem carefully. "Which choice best maintains the tone?" is a different question than "Which choice provides the most specific detail?"

ACT Math: Algebra, Geometry, and Trig
The Math section gives you 60 questions in 60 minutes. It covers pre-algebra through early trigonometry, with the difficulty generally increasing as you move through the test. You can use a calculator on the entire section, and the digital ACT provides a built-in Desmos graphing calculator.
Key strategies:
- Know the content. Unlike other sections where strategy can compensate for knowledge gaps, ACT Math requires you to actually know the formulas and concepts. There is no passage to reference.
- Do easy questions first. Questions 1 through 30 are easier and worth the same as questions 50 through 60. Make sure you nail the first half before spending time on hard problems.
- Use your calculator strategically. It speeds up arithmetic and graphing but slows you down if you rely on it for every problem. Know when to calculate mentally.
- Plug in answer choices when you are stuck. This backward-solving approach works on roughly 20% of ACT Math questions.
Our ACT Math prep guide covers every topic you will see, and the ACT Math formula cheat sheet gives you every formula worth memorizing.
ACT Reading: Speed and Comprehension
The Reading section gives you 40 questions in 35 minutes across 4 passages. That is less than 9 minutes per passage, which is the tightest time crunch on the ACT. The four passages always appear in the same order: Prose Fiction (or Literary Narrative), Social Science, Humanities, and Natural Science.
Key strategies:
- Do not read every word. Skim the passage in 3 to 4 minutes, focusing on the main idea of each paragraph and the author's overall argument. Then spend 5 minutes answering questions.
- Do passages in your strongest order. If you are better at Social Science than Prose Fiction, start there. You can answer passages in any order.
- Every answer is in the passage. The ACT Reading section never requires outside knowledge. If you cannot point to the specific line that supports your answer, you are probably wrong.
- Watch for "almost right" answer choices. The ACT is very good at creating choices that are 80% correct but include one wrong detail. Read every word of every answer choice.

ACT Science (Optional): Data Interpretation
If you choose to take the optional Science section, you get 40 questions in 35 minutes across 6 to 7 passages. The section tests data interpretation, experimental reasoning, and evaluation of competing hypotheses. It does not test science knowledge.
Key strategies:
- Go straight to the questions. For Data Representation and Research Summary passages, skip the introduction and let the questions guide you to the relevant figures.
- Only read fully for Conflicting Viewpoints. This is the one passage type that requires careful reading before answering.
- About 95% of answers come from the passage. Only 2 to 4 questions per test need basic outside knowledge (pH scale, cell biology, simple physics).
Our ACT Science section guide covers the full format, and our Science ACT tips article has passage-by-passage strategies.
Step 4: Practice the Right Way
Studying and practicing are two different things. Studying is learning content and strategies. Practicing is applying them under test-like conditions. You need both, in the right order.
Phase 1: Untimed Practice (Weeks 1-4)
Start with untimed practice to build accuracy. There is no point adding time pressure before you understand the question types. During this phase:
- Work through individual passages without a clock
- Review every wrong answer immediately. Do not just check the answer key. Understand why the correct answer is right and why yours was wrong.
- Keep an error log. Write down the question type, what you got wrong, and why. Patterns will emerge quickly.
Phase 2: Timed Sections (Weeks 5-8)
Once your accuracy is solid, add the clock. Time individual sections (not full tests yet) and track both your score and your pacing.
- If you are finishing with time to spare but making errors, slow down slightly and focus on accuracy
- If you are running out of time, practice skipping hard questions and returning to them later
- Take one timed section per study session, then review thoroughly
Phase 3: Full-Length Tests (Weeks 9-11)
Full-length practice tests under real conditions are the most valuable part of your prep. They build stamina, reveal how fatigue affects your performance, and simulate the real experience.
- Take at least 4 to 6 full-length tests before your real test date
- Simulate everything: timing, breaks, no phone, quiet environment
- Score each test and do a thorough review of every wrong answer the same day
The Official ACT Prep Guide includes four full-length authentic tests. Supplement those with practice quizzes on Larry Learns to drill specific sections between full tests.
Step 5: Choose the Right Resources
You do not need to spend a fortune on ACT prep. Here is what is worth your time and money.

Step 6: Master Test Day Strategies
Content knowledge and practice get you most of the way there. These test-day strategies get you the rest.
Guessing Strategy
There is no penalty for wrong answers on the ACT. Never leave a question blank. If you are stuck, eliminate what you can and guess from the remaining choices. Even random guessing gives you a 25% chance, and strategic elimination pushes that to 33% or 50%.
Time Management
The Night Before and Morning Of
- Night before: Light review only. No cramming. Get 8 hours of sleep. Pack your bag (ID, calculator, pencils, snacks, water).
- Morning of: Eat a solid breakfast with protein and complex carbs. Arrive early. Do a few warm-up questions from your phone to activate your brain.
- During breaks: Eat a snack, drink water, stretch. Do not discuss answers with other students. Stay in your zone.
Common ACT Prep Mistakes to Avoid
- Studying without a plan. Random practice is better than nothing but dramatically worse than structured prep. Set a schedule and stick to it.
- Spending equal time on all sections. Your weakest section is where the biggest point gains are. Prioritize it.
- Never reviewing wrong answers. Taking practice tests without reviewing them is the biggest waste of time in test prep. The review is where learning happens.
- Only doing untimed practice. Accuracy without speed does not translate to ACT scores. Start adding time pressure by week 5 of your prep.
- Cramming the week before. The ACT tests skills built over weeks and months, not facts memorized yesterday. The final week should be light review and rest.
- Using only non-official materials. Third-party practice tests are useful, but nothing matches the style and difficulty of official ACT questions. Use the real thing for your full-length practice tests.
- Ignoring the essay if your schools want it. Some colleges still request the Writing section. Check requirements before assuming you can skip it.
ACT vs. SAT: Which Test Should You Take?
Many students wonder whether to take the ACT, the SAT, or both. The short answer: take a practice test of each and see which one you score higher on. They are accepted equally by virtually all U.S. colleges.

Frequently Asked Questions About How to Prep for the ACT
How long does it take to prep for the ACT?
Most students need 2 to 3 months of consistent study (6 to 10 hours per week) to see a meaningful score improvement of 4 to 6 points. If you are starting well below your target or aiming for a 30+, plan for 4 to 6 months. The key is consistency: studying 1 hour per day is more effective than cramming 7 hours on the weekend.
Can I prep for the ACT on my own without a tutor?
Yes. Self-study works well for disciplined students who can stick to a schedule. Use official practice tests, a good prep book, and an online platform like Larry Learns for adaptive practice. A tutor helps most when you are stuck on specific content gaps or need accountability, but plenty of students reach 30+ scores through self-study alone.
What is the best ACT prep book?
The Official ACT Prep Guide 2025-2026 is the single most important resource because it contains real ACT questions. For strategy and content review, The Princeton Review's ACT Premium Prep and Kaplan's ACT Prep Plus are both solid choices. Read our best ACT prep books guide for detailed reviews.
How many practice tests should I take before the real ACT?
Aim for at least 4 to 6 full-length timed practice tests. Space them out across your prep, ideally one every 2 weeks starting from week 5 or 6 of your study plan. Always do a thorough review of every wrong answer after each test. Quality of review matters more than the number of tests you take.
Is the ACT Science section still required?
No. Starting in 2025, the ACT Science section is optional and no longer counts toward your composite score. Your composite is now the average of English, Math, and Reading only. However, some schools still require it. Check your target colleges before deciding to skip it. The section costs an extra $4.
What is a good ACT score for college?
It depends on where you are applying. A 21 is the national average. A 25 or above is competitive for many four-year colleges. A 30 or above puts you in the top 7% and is competitive at most selective universities. A 34+ is competitive for Ivy League schools. Look up the middle 50% range for your target schools to set a realistic goal.
Should I take the ACT or the SAT?
Take a timed practice test of each and compare your scores. Both tests are accepted by virtually all U.S. colleges. The ACT favors fast readers with strong data interpretation skills. The SAT favors careful thinkers with strong algebra and vocabulary skills. Choose whichever test you naturally score higher on and focus your prep there.
