About ACT
The ACT is the SAT's main competitor for US college admissions, accepted by every US university. Unlike the SAT, the ACT includes a dedicated Science section and is non-adaptive. It has 4 sections — English, Math, Reading and Science — plus an optional Writing (essay) section. Each of the 4 core sections scores 1–36, and the composite is the average, giving a 1–36 composite score. Jarvis AI supports ACT candidates with section-specific tutoring, full-length timed mocks, an essay-grading rubric aligned with ACT scorers and composite score prediction.

Grading & scoring
Each section scores 1–36; composite is the average rounded to the nearest whole number. Writing scores 2–12 separately. Score reports include percentile ranks and college-readiness benchmarks.
Exam strategy & time management
- 1The ACT rewards pace — most students run out of time in Reading and Science. Practise finishing every passage in 8:45.
- 2In Science, the questions test data interpretation, not scientific knowledge — read the graphs before the passage.
- 3In English, most 'no change' answers are wrong on structure questions but right on style questions. Learn the pattern.
- 4Skip and return — the ACT MCQ questions are not weighted, so easy questions late in the section are worth as much as hard early ones.
Common mistakes to avoid
- ✕Reading Science passages word-for-word instead of scanning graphs first.
- ✕Over-thinking English 'no change' options.
- ✕Running out of time in Reading by lingering on the first passage.
- ✕Ignoring the Writing prompt's three perspectives — you must engage with them for a top score.
ACT FAQ
SAT or ACT — which is better?
Both are accepted equally. Students who prefer science and pace pressure tend to prefer the ACT; those who prefer reading depth and adaptive difficulty tend to prefer the SAT. Take a diagnostic of each on Jarvis to compare.
Is the ACT changing format?
Yes — from 2025 the ACT is moving to a shorter, more flexible format with an optional Science section. Jarvis's mocks reflect the current spec.
How is the ACT essay scored?
Two graders score 1–6 on each of four domains (Ideas & analysis, Development & support, Organisation, Language use). Jarvis grades essays against the official rubric.
What ACT score do I need for a top university?
The 25th–75th percentile at top-tier US universities is typically 33–36. Jarvis predicts your composite from practice performance.
