How to Score a 20 on the ACT | ScoreSmart Strategy

Table Of Contents

A 20 on the ACT is the national average. It puts you right in the middle. And it is very reachable.

You do not need to be a genius. You do not need to study for 100 hours. You just need a smart plan and some honest practice.

Here is exactly “How to Score a 20 on the ACT?”


What Is a 20 on the ACT?

The ACT is scored from 1 to 36. Your score is the average of four sections: English, Math, Reading, and Science.

A 20 means you are getting about half the questions right on each section. That is a solid, real goal for most students.


Step 1: Take a Practice Test First

Before you study anything, take a full practice test.

This tells you where you are right now. It shows you which sections are strong and which ones need work.

Do not skip this step. Studying without knowing your weak spots is a waste of time.

You can take a free full-length ACT practice test at ScoreSmart. It scores instantly and shows you exactly where you lost points.


Step 2: Find Your Weak Section

Look at your four section scores: English, Math, Reading, Science.

Which one is the lowest? That is where you start.

Raising a weak section from a 15 to a 20 is easier than raising a strong section from a 22 to a 27. Focus on the bottom first.


Step 3: Learn the Format of the Test

The ACT is the same every time. Same sections. Same question types. Same timing.

When you know the format, nothing surprises you on test day.

Here is the breakdown:

ACT Test Sections Explained

Section Questions & Time What It Tests
English 75 Questions • 45 Minutes Grammar, punctuation, sentence structure, and writing skills.
Math 60 Questions • 60 Minutes Algebra, geometry, coordinate geometry, and basic trigonometry.
Reading 40 Questions • 35 Minutes Reading comprehension, passage analysis, and understanding written content.
Science 40 Questions • 35 Minutes Interpreting charts, graphs, data tables, and scientific information.

Step 4: Practice the Right Way

Most students just read and re-read notes. That does not help much.

The best way to improve is to do practice questions, get them wrong, and then understand why you got them wrong.

When you miss a question, ask yourself: “What did I not know?” Then learn that one thing.

One mistake fixed is better than one hour of reading notes.


Step 5: Work on Timing

Running out of time is one of the biggest reasons students score below 20.

You have about 30 to 45 seconds per question on most sections. Practice working at that pace.

If you are stuck on a question, skip it. Come back later. Never let one hard question eat up all your time.


Step 6: English Section Tips

This section tests grammar rules. The good news: there are not that many rules.

Focus on these:

  • Commas (when to use them and when not to)
  • Subject-verb agreement (“The group of students WAS” not “WERE”)
  • Apostrophes (its vs. it’s)
  • Sentence fragments
  • Transitions (words like however, therefore, because)

Learn these five things well and you will get a lot more questions right.


Step 7: Math Section Tips

You do not need advanced math to score a 20.

Most of the questions you need to get right are basic algebra and geometry. Focus on:

  • Solving for x
  • Fractions and percentages
  • Lines and slopes
  • Area and perimeter of basic shapes
  • Word problems

Skip the hard questions (usually the last 10 to 15). Get the easy and medium ones right first.


Step 8: Reading Section Tips

There is no shortcut here. You have to read fast and stay focused.

Try this: read the questions before you read the passage. Then when you read, you know what to look for.

Always go back to the passage to find your answer. Do not answer from memory.


Step 9: Science Section Tips

Here is the secret about the Science section: it is not really a science test.

It is a reading-charts-and-graphs test. You do not need to memorize biology or chemistry facts.

Just read what the data is showing you. The answer is almost always right there in the graph or table.


Step 10: Take More Practice Tests

After you study, take another practice test. See if your score went up.

Repeat this cycle: test, review, study weak spots, test again.

Each test you take, you get a little better. Students who take 3 to 5 practice tests usually see real score gains.


How Long Will It Take?

Most students can go from a 15 to a 20 in about 4 to 6 weeks. Some do it faster.

Study 30 to 45 minutes a day. That is enough. Consistency beats cramming.


Quick Summary

  1. Take a free practice test to see where you are
  2. Focus on your lowest section first
  3. Learn the test format inside and out
  4. Practice questions and review your mistakes
  5. Work on your timing
  6. Take more practice tests and track your progress

A 20 is not out of reach. It just takes the right plan.
