PreACT 9 Topic Breakdown

*The PreACT 9 includes experimental questions in each section which do not count towards a student’s score.

English

The English test measures your understanding of effective writing. The test includes three passages in which certain phrases or sentences are underlined. You will need to choose the multiple-choice answer that best completes each passage based on your knowledge of grammar, punctuation, topic organization, word choice, style, and tone.

Math

The math test measures your ability to solve problems using logical reasoning rather than memorizing complex formulas. You will answer questions related to number and quantity, algebra, functions, geometry, and basic statistics.

Reading

The reading test measures your reading comprehension and logical thinking abilities. The test includes three longer passages and a pair of shorter passages drawn from literary narratives and informational texts, such as those in the humanities, natural sciences, and social sciences. You will answer questions related to main ideas and details, structure and purpose, and cross-text connections.

Science

The science test measures your ability to interpret and analyze scientific information. The test includes several passages about topics like biology and ecology, chemistry and physics, and Earth and space science. The information is presented using reading passages as well as graphs and figures. Questions will ask you to interpret the data in the passage, understand experimental tools, methods, and design, and draw conclusions and make predictions based on the text.

Breaking Down the Four Sections on the PreACT 9

Recently, it was announced that Chicago Public Schools has replaced the CPS HSAT with the PreACT 9 Secure, a nationally recognized assessment that is now being administered to rising Chicago 8th-graders as part of the Selective Enrollment High School admissions process.

The change represents far more than a simple name swap. The PreACT 9 is a fundamentally different type of exam. While the CPS HSAT was built specifically for CPS admissions, the PreACT 9 was created to measure academic readiness and predict future success on the ACT, the college entrance exam many students take during high school. As a result, families are encountering a test that is longer, more comprehensive, and more closely aligned with the skills students will need throughout high school and beyond.

One of the first things families notice about the PreACT 9 is its length. The exam includes four separate sections (English, Math, Reading, and Science) and requires students to maintain concentration for two and a hours. Success on the exam depends not only on academic ability, but also on a student's capacity to stay focused and work efficiently over an extended period of time. Here is a breakdown of each of the sections seen on the PreACT 9:

The English section focuses on grammar, sentence structure, punctuation, usage, and writing effectiveness. Students are presented with passages and asked to identify the best revisions, correct grammatical errors, improve sentence flow, and strengthen organization. Questions frequently require students to understand comma usage, subject-verb agreement, sentence boundaries, transitions, and word choice. Students are tested on writing production (27-33% of questions), language knowledge (12-18% of questions), and English conventions (48-55% of questions), and students are given 35 minutes to answer 44 questions.

The Math section combines computational skills with higher-level reasoning. Students encounter questions involving algebra, geometry, ratios, proportions, statistics, and data analysis. Students must analyze information, interpret graphs, and choose efficient solution strategies while managing strict time limits. Students are tested on the real number system (10-13% of questions), algebra (20-27% of questions), functions (20-27% of questions), geometry (10-13% of questions), and statistics/probability (10-13%), and are given 45 minutes to answer 35 questions.

The Reading section involves reading passages drawn from literature, social studies, humanities, and science before answering questions that assess comprehension and analytical thinking. Rather than focusing solely on straightforward details, many questions require students to infer meaning, identify an author's purpose, evaluate tone, and determine how evidence supports an argument. The challenge lies in balancing speed with accuracy; students must process substantial amounts of information without sacrificing careful analysis. Students are tested on key ideas and details (52-60% of questions), craft and structure (28-36% of questions), and integration of knowledge and ideas (12-16% of questions), and are given 40 minutes to answer 33 questions.

For the Science section, many students enter the test expecting questions that emphasize memorized scientific facts, formulas, or vocabulary. Instead, the Science section is largely an exercise in data interpretation and reasoning. Students are presented with science-oriented reading passages, graphs, charts, experimental results, and research summaries. They must identify trends, evaluate conclusions, compare experimental designs, and draw logical inferences from evidence. In many cases, prior scientific knowledge plays a smaller role than the ability to analyze information quickly and accurately. Students who are comfortable reading tables and scientific passages, as well as interpreting visual data often perform well, even if they do not consider science to be their strongest subject. Students are tested on interpretation of data (23-50%), scientific investigation (15-35% of questions), and evaluation of models, inferences, and experiments (19-38% of questions), and are given 35 minutes to answer 32 questions.

Beyond the test itself, one of the most significant features of the PreACT 9 is the detailed score report students receive afterward. Unlike many admissions exams that provide only a single score, the PreACT 9 offers a comprehensive breakdown of performance across multiple areas. Students receive individual scores for English, Math, Reading, and Science, along with an overall composite score that reflects their performance across the entire assessment. This allows families to see where students excel and where additional support may be needed.

Why Test Prep Matters for the ACT: How Practice Makes Perfect

The ACT is more than just a test of what you know in math, English, reading, and science–it’s a test of how well you can apply those skills under time pressure. For many students, the difference between an average score and a standout score doesn’t come down to intelligence or effort in school, but to preparation. This is where focused ACT test prep makes a real and measurable difference.

Practice is essential for the ACT because it has its own structure, pacing, and logic. Even strong students can struggle if they aren’t familiar with the way questions are worded or how quickly they need to move through each section. Regular practice with practice exams, material seen on the exam, and keeping time helps students recognize patterns, anticipate common traps, and build confidence with the test format. Over time, this familiarity reduces anxiety and allows students to focus on accuracy rather than panic. The ACT is quite fast-paced, and, as such, while many students may know the material, they can still simply run out of time. Through consistent practice, students learn pacing strategies, when to move on from a difficult question, and how to maximize points by prioritizing accuracy on questions they can control. These are skills that rarely develop on their own without guided practice and feedback.

Targeted ACT prep also helps students identify and strengthen their weaknesses. Practice tests reveal patterns—maybe grammar rules are costing points in English, or data interpretation is an issue in Science. Once those gaps are clear, focused tutoring can turn weak areas into strengths. Instead of studying everything at once, students learn how to study smarter, not longer.

At Test Prep Chicago, we are a proud Licensed Provider of Official ACT® Content, our material includes Officially Licensed ACT® Content, making our practice tests some of the most accurate out there. We often see firsthand how structured preparation changes outcomes for students, regardless of where they are in their ACT prep journey.

New: Mindset Reflections for ACT & SAT Prep Students Taking Practice Exams

Have a student enrolled in one of Test Prep Chicago’s ACT or SAT Prep courses, one-day workshops, or individual tutoring? We have great news: TPC has now implemented new, advanced analytical tools on our testing platform, Testpress, to help your student better understand their performance on our practice exams.

Once a student completes a Diagnostic or Final exam with us as part of one of our courses, or a Palooza Test as part of one of our one-day workshops, they receive access to detailed testing analytics, including information on their performance on each section, how many questions they left unanswered, how long they took on each question and each section, and more. Students also receive access to answer explanations for each question seen on the exam, regardless of whether they got it correct or not. 

Additionally, as students review the provided answer explanations for each question, they are now able to submit Mindset Reflections for any questions they answered incorrectly. Once submitted, students can access a detailed breakdown of their reflections, along with insights drawn from the pre- and post-exam questionnaires. This tool helps students understand why mistakes are occurring, identify recurring error patterns, and receive tailored test-taking strategies to support meaningful improvement as they continue to work toward success on the ACT and SAT.

If there is ever any confusion regarding how to use TPC’s Mindset Tool or access analytics on Tespress, students and parents alike can refer to our Testpress Tutorial Video (linked here). This video provides a step-by-step overview of how to log in to the platform, access materials, retake exams, review testing analytics, submit Mindset Reflections, and interpret the results.

How Selective Enrollment Schools Use the CPS HSAT: Why It Matters & What It Tests

For students applying to Chicago's selective enrollment high schools, the CPS High School Admissions Test (CPS HSAT) is a major factor that is worth 50% of the total admission score. CPS uses a 900-point system to evaluate applicants: 450 points from 7th grade grades in core classes (reading, math, science, and social studies), and 450 from the CPS HSAT. That means doing well on the test can significantly impact whether a student receives an offer from a top selective enrollment high school.

The CPS HSAT is taken in the fall of a student's 8th grade year and includes two main sections: math and reading comprehension. It is a timed, multiple-choice test, 1-hour in length, that is administered digitally at the student's school (if they are a CPS student) or at a CPS-designated test center (if they are a non-CPS student). The math section includes algebra, data analysis, number operations, geometry, and problem-solving, while the reading section focuses on comprehension, vocabulary in context, and inference-based questions. There is no penalty for wrong answers, so students should be prepared to strategically guess if necessary.

Because students come from so many different schools and grading systems, the CPS HSAT serves as a standardized way for selective enrollment high schools to compare applicants across the city. It's not just about content knowledge, but also about how well students manage time and pressure. That's why preparation matters.

At Test Prep Chicago, we prepare students for every topic covered on the CPS HSAT. Our group courses (click here), 1-day workshops (click here) and individual tutoring sessions (click here) include full-length practice tests, targeted homework, and supplemental materials designed to strengthen skills and build confidence over time. Our tutors teach proven test-taking strategies, time-management techniques, and pacing skills to help students stay sharp and focused on test day. By conducting exit interviews with students after they take the real exam, we are able to ensure our practice materials are constantly updated to reflect the latest test trends and content. 

If you're looking for supporting and strategic preparation for the CPS HSAT, TPC Is the place to start.

ACT Enhancements

The ACT has made major structural changes to the exam that will be implemented in the coming months. The ACT will now have 44 fewer questions and students will receive more time to answer each question. The length of the test in total will be reduced to 125 minutes rather than 195 minutes as in previous years. Students will also have the option to opt out of the science section unlike previous years.

Math and English portions of the exam will be adjusted slightly. For math questions, the ACT will be eliminating a response option from each question. Options that are rarely chosen or of poor quality will be removed from the exam, leaving four potential answers rather than five. Additionally, when questions contain a graphic, answer options that can be easily eliminated by looking at the image will be removed from the test. This is designed to match the format of other assessments and improve the test-taking experience for students.

During the English section, students will be provided with clear instructions for each question. Previously, portions of text would be underlined or numbered to denote which phrases pertain to each grammar and language question. However, no instructions were given for each individual question, so students needed to reference the instructions at the beginning of the section. This will no longer be the case, as the ACT will provide instructions for each question such as “which choice makes the sentence most grammatically acceptable?” followed by the answer choices. Additionally, the “No Change” options will be bolded so they are easier to see. These changes are being introduced to promote clarity for all students.

ACT enhancements will begin going into effect starting in April of 2025 for students taking the exam online. By September of 2025, all students taking the exam on paper or online will receive these benefits as well. The adjustments will be reflected in all schools and districts by spring of 2026.
