How Trellis Prepares You
Pacing Is Everything
The ACT is a speed test. You get roughly 36 seconds per Science question. Trellis drills pacing until it's automatic.
Section-by-Section
Diagnostic testing identifies your weakest section. Most students gain the most points by focusing on their worst area first.
Science Demystified
ACT Science isn't about memorizing facts. It's about reading graphs fast. Trellis teaches the specific skills this section requires.
Instant Explanations
Every wrong answer gets a detailed walkthrough. Ask follow-up questions until you understand the reasoning completely.
ACT vs SAT: Which Should You Take?
Both tests are accepted by virtually all US colleges. The ACT tends to favour students who work quickly and have strong science literacy. The SAT tends to favour students who are comfortable with multi-step reasoning and evidence-based analysis.

ACT Science: What It Actually Tests
The ACT Science section confuses many students because it doesn't test science knowledge. It tests your ability to read and interpret scientific data quickly. You'll see experiments you've never heard of — and that's fine. The answers are always in the graphs, tables, and passage text.
Trellis teaches the three question types (data representation, research summaries, conflicting viewpoints) with hundreds of practice passages. Most students see significant improvement in just 2-3 weeks of focused Science practice.
