English + Math + Reading + Science, without the AI shortcut.
The ACT is 215 questions across four scored sections (plus an optional Writing) in 2 hours 55 minutes. That's an average of 49 seconds per question. Fluency of reasoning — not depth, not creativity, but speed of the reasoning act — is what the test rewards.
Students who go into the ACT thinking they need to 'understand every question thoroughly' finish 5 sections without completing them. Students who train for fluency finish with time to spare and check their work. The training difference is not depth; it's rehearsal.
Brainback trains fluency by making the attempt-first workflow the default. Every practice question runs through Learn mode with the attempt-gate on. Wrong answers become spaced-recall cards. Grammar rules, math formulas, and Science-passage inference patterns get retrieved on the SM-2 schedule until they're second-nature.
We publish no composite-gain figure, because we have run no study to produce one. The claim we will make is about the source: the drills are written from your own official practice tests and class material, cite the page they came from, and return on a schedule rather than being reviewed once and filed.
Total: 2 hours 55 minutes (3h35m with optional Writing). Below is every section, with its duration, question count, and scoring role.
| section | duration | questions | scoring |
|---|---|---|---|
| English | 45 min | 75 | 1-36 |
| Math | 60 min | 60 | 1-36 |
| Reading | 35 min | 40 | 1-36 |
| Science | 35 min | 40 | 1-36 |
| Writing (optional) | 40 min | 1 essay | 2-12 |
Each section 1-36. Composite 1-36 (average of four). National average ~20.7. Ivy/Top-20 competitive: 34+. National merit: 32+.
Rehearsable. Predictable. Adjustable for your calendar. Each week has one focus and one specific Brainback move.
| when | focus | brainback move |
|---|---|---|
| Month 1 | Diagnostic + English/Math foundations | Full-length practice ACT. Note baseline. Recall queue starts on grammar + formulas. |
| Month 2 | Reading + Science technique | Reading and Science are pacing-heavy. Timed passages 3x/week; explain-back on inference patterns. |
| Month 3 | Timed full-length weekly | One full-length Saturday, error review Sunday. Any section < 25 gets extra time. |
| Month 4-6 | Weakness kill + timing polish + rest | Any question type < 80% gets an extra 30 min daily. Rest week final 5 days. |
Take a full-length practice ACT under real conditions (35 min English, 60 min Math, 35 min Reading, 35 min Science). Score it.
A representative exchange: the problem, your attempt, the tutor’s response, your follow-up, the downstream card. Notice the tutor never solves.
Science passage: A graph shows enzyme activity vs. temperature, peaking at 40°C and dropping sharply above 45°C. What does the sharp drop most likely indicate?
The enzyme stops working at high temperatures.
Right direction, but the ACT wants you to name the MECHANISM, not just the outcome. What physically happens to a protein at temperatures above its optimal range?
The enzyme denatures — its 3D structure unfolds and it can no longer bind substrate.
All seven product surfaces are always on. For this exam specifically, these three carry the load. Each has its own dedicated page.
And the specific Brainback mechanism that catches each one. This isn’t a promise — it’s what the workflow is designed to do.
Running out of time on Science (last section)
Weekly timed Science practice from month 2 onward builds the pacing endurance the actual test demands.
Grammar rules half-remembered on English section
Recall queue keeps ~30 core grammar rules retrievable in under 5 seconds.
Careless arithmetic errors on Math
Explain-back on math setups forces you to state the reasoning aloud (in text) — the reasoning error becomes visible before the calculation error.
Common approaches that feel productive but produce nothing. Skipping these is worth as much as adding a technique.
because · Test fatigue is real. 3-4 full-lengths in the final month is the ceiling; more produces diminishing returns and burnout.
because · Many colleges still consider it. Efficiency mode can help you outline; Learn mode grades your structure.
because · Official ACT practice tests are the closest thing to the real test. Use them as primary; third-party as supplement.
No published point range — we have not run the study that would earn one. The structural fact about the ACT is 49 seconds per question, which means the test rewards retrieval speed rather than depth. Spaced recall is the only part of the stack that trains retrieval speed directly, which is why the queue, not the question volume, is the thing to keep honest.

Both are accepted at essentially all US colleges. Take a diagnostic of each; go with your stronger score. Our workflow works identically for both.
Learn mode helps with argument structure + counter-argument identification. Efficiency mode never touches ACT prep — it's a graded exam.
Same Socratic loop: name the graph type, identify the trend, evaluate the hypothesis. Attempt-first, hint if stuck, no answer given away.
Yes — superscoring is common. Most students who go from 26 to 32 do so across 2-3 sittings. Brainback shortens the gap between sittings.
Digital ACT is being rolled out globally; content is identical to paper. Bluebook-equivalent practice available in the ACT prep app. Practice under whatever mode you'll take the real test in.
The years when learning habits either form or don't. Brainback makes the habit inevitable.
