Why ACT Prep Mistakes Matter More in 2026
With the ACT's updated format—optional Science, a composite based only on English, Math, and Reading—many students are using outdated strategies or making choices that waste time and cost points. Avoiding these mistakes can save weeks of prep and add real points to your score.
Mistake #1: Ignoring the Optional Science Decision
The mistake: Treating Science as if it's still required—or skipping it without a plan.
The fix: Decide intentionally. If you're targeting STEM, take Science and prep for it. If not, skip it and reinvest that time into English, Math, and Reading—the only sections that affect your composite. ACT Radar helps you see whether Science adds value for your goals.
Mistake #2: Studying Every Topic Equally
The mistake: Covering the entire syllabus without prioritizing high-impact topics.
The fix: Focus on what actually appears. The ACT tests certain concepts far more often than others. ACT Radar identifies high-frequency, high-impact topics so you study what raises your score fastest—not what feels "complete."
Mistake #3: Neglecting Pacing and Time Management
The mistake: Knowing the content but running out of time or rushing.
The fix: Practice under timed conditions from day one. Use section checkpoints, track time per question type, and identify where you slow down. ACT Radar's pacing insights help you build speed without sacrificing accuracy.
Mistake #4: Not Analyzing Your Mistakes
The mistake: Doing practice questions without reviewing why you got them wrong.
The fix: Every error has a pattern—misread the question? Skipped a step? Wrong formula? ACT Radar surfaces your recurring mistake types so you fix the root cause instead of repeating the same errors.
Mistake #5: Relying on Outdated Prep Materials
The mistake: Using old books or courses that assume Science is required or that the format hasn't changed.
The fix: Use resources that reflect the 2025–2026 ACT. ACT Radar uses real, up-to-date exam data to predict what matters—so your prep matches what you'll actually see on test day.
Mistake #6: Cramming Instead of Spacing Out Prep
The mistake: Waiting until the last few weeks and cramming full-length tests.
The fix: Start early and use short, targeted drills. ACT Radar's precision sessions (15–20 minutes) beat marathon cramming. Spaced practice improves retention and reduces burnout.
Mistake #7: Skipping Practice for Your Weakest Sections
The mistake: Avoiding the sections you dislike or find hard.
The fix: Your composite is the average of English, Math, and Reading. One weak section pulls down the whole score. Use ACT Radar to identify weak areas and attack them first—they often offer the biggest score jumps.
