ACT Complete's Smart Study mode automatically identifies what you need to work on and builds a personalized practice plan around it — but how much time should you actually expect to spend? This article gives you a real, calculated estimate based on a tested formula, and shows you exactly how to personalize it using your own results inside ACT Complete.

How ACT Complete Builds Your Study Plan Automatically

Instead of guessing where to focus, ACT Complete tracks your accuracy across every topic group in English, Math, Reading, and Science. Smart Study uses that data to recommend exactly what to practice next — so your time is always spent on the areas most likely to raise your score, rather than re-practicing material you've already mastered.

That automatic guidance solves what to study. This article solves the next question: how long it's likely to take.

A Typical Time Estimate for Each Section

To estimate total study time, we take the time it takes to master one representative topic group in a section, then extrapolate that across all the topic groups in that section. We then add time for a second pass through roughly half the material, two full timed practice tests, and strategy review.

The Formula (per section)

1st Round Estimate = (minutes to master one sample topic) × (number of topic groups in that section)
2nd Round Estimate = 1st Round × 0.5 (revisiting roughly half the material)
Section Total = 1st Round + 2nd Round + Practice Test Review Time + Strategy Study Time

Using sample data — 10 minutes to master "Adjectives & Adverbs" in English, 10 minutes for "Conics" in Math, 10 minutes for "Little Picture" in Reading, and 0 minutes for "Comparing Viewpoints" in Science (a topic many students already know) — here's how the estimate breaks down:

Section Topic Groups Total Time (minutes) Total Time (hours)
English×25695 min~11.6 hrs
Math×501,185 min~19.75 hrs
Reading×5435 min~7.25 hrs
Science×8370 min~6.2 hrs
Total2,685 min~44.75 hrs

Excluding the optional Science section, the total comes to roughly 38.6 hours. This lines up closely with the 40–100 hour range research suggests for meaningful ACT score improvement — Math typically requires the most time because it covers the widest range of distinct topic groups.

Important

This is a sample estimate using representative numbers, not your personal estimate. Every student masters topics at a different pace — the next section shows you how to plug in your own numbers using ACT Complete.

Personalize Your Estimate Using ACT Complete

To get an estimate based on your own pace rather than a sample average, follow these steps inside ACT Complete:

  1. 1

    Open ACT Complete, select View All Topics, and click "Adjectives & Adverbs" under "Conventions of Standard English." Answer all 5 questions, reviewing the feedback for each until you reach the level of mastery you want.

  2. 2

    ACT Complete will display how long that took you. Multiply that number by 25 (the number of topic groups in English) to get your personalized 1st Round Estimate for English.

  3. 3

    Repeat the process with "Conics" under "Coordinate Geometry." Multiply your time by 50 for your Math estimate.

  4. 4

    Repeat with "Little Picture" under "Identify Ideas." Multiply your time by 5 for your Reading estimate.

  5. 5

    If you plan to take the ACT Science Test, repeat with "Comparing Viewpoints." Multiply your time by 8 for your Science estimate.

  6. 6

    Add the 2nd Round Estimate (half of each 1st Round number), plus practice test review time and strategy study time, to get your personalized total — using the same formula shown above.

What's Included in the Total Estimate

The full study time estimate accounts for four components:

A Smarter Way to Practice Math

Instead of taking multiple full-length Math practice tests, identify which categories of math questions need the most work and run smaller, targeted practice sets on those specific areas. There's little value in repeatedly solving problems you already know how to do — the score gains come from the problems you're currently missing.

Turning Your Estimate Into a Weekly Study Schedule

Once you have a total hours estimate, the next step is spreading it across the weeks you have before your test. Research consistently shows that successful ACT preparation depends on:

Using the sample estimate of 44.75 total hours, here's how that translates into a weekly commitment depending on your timeline:

Timeline Hours per Week
8 weeks~5.6 hours/week
12 weeks~3.7 hours/week
16 weeks~2.8 hours/week

The number that matters most isn't the total — it's translating it into specific days and times on your calendar. A "study when I can" approach tends to quietly become "I didn't study much." For example, to hit 4 hours per week, you might commit to one hour at 8 PM Tuesdays, one hour at 7 PM Thursdays, and two hours starting at 11 AM Saturdays.

Bottom Line

Your personalized number — calculated from your own pace in ACT Complete — will be more accurate than any generic estimate. Use it as a starting point, then adjust as you go. The total will shift as you get faster and more accurate with practice.
