Where the difference between passing and mastering is a habit, not a talent.
College courses reward the students who can reason under pressure. Brainback is where that reasoning is trained — during problem sets, essay drafts, and lab writeups — instead of outsourced. Efficiency mode handles the drafting, scheduling, and life admin around the courses that actually matter.
Cancel the other AI subscription in the first week. Efficiency mode makes it redundant, and closing the loop mentally is what makes Learn mode work for coursework.
An honest before-and-after — the specific gaps Brainback closes for a student in this stage of the arc.
Same problem. Same student. Two different definitions of “productive.”
The actual daily shape of a Brainback week for this stage. Adjust for your own load — the rhythm compounds even if the volume varies.
20 recall cards. One Learn session on the biggest PSet due Thursday.
Same. Add explain-back on today's new lecture concept.
Efficiency mode drafts the response to your TA. 10 cards. Full Learn session on shaky material.
PSet due. Explain-back on the trickiest problem after submitting.
10 cards. Free evening. You've earned it.
Optional catch-up. If you have a midterm, this is where the deliberate practice happens.
Brain score arrives. 10 cards. Look at the trend. Adjust for the week.
None of these are automatic. Each is a signal that the product is working — or isn’t. If you don’t hit the week-4 milestone, revisit the plan.
First 'oh — that's what that concept meant' from an explain-back.
First PSet submitted where you understood every problem, not just answered it.
First honest Brain score. 60s are normal. Trend > absolute value.
First midterm that feels like a checkpoint, not an ambush.
Grade closely tracks the trailing 12-week Brain score. That's when the product has fully landed.
Not a magic diet. A specific sequence of habits Brainback builds around you. The pace is designed for a student with a normal life outside coursework.
Add every class as a Learn subject. Attach syllabi to each. This is the day you cancel the other AI subscription.
Every problem set gets one Learn session. Every essay outline gets one explain-back. Ignore Brain score — it's calibrating.
First real Brain score. Note the lowest subject. Set aside 30 min/day for it until the number moves.
Recall queue becomes the morning routine. 10 cards with coffee. Explain-backs replace the mental rehearsal you used to try to do in the shower.
Midterms feel like measurements, not ambushes. Group chats start asking 'what's your Brain score in P-Chem?' un-ironically.
The recall queue has been catching everything since week 3. Finals are checkpoints, not first exposures.
All seven product surfaces are always on. But this stage of the arc weights them differently. Below are the ones a college student ends up leaning on hardest.
Every PSet, every essay draft, every lab writeup runs through here.
The intellectually-honest version of 'send me #7.'
Say the concept back in your own words; the rubric scores the gap, 0–5.
Week 3 material still alive in week 15. The whole point.
So you can cancel the other AI subscription without losing draft-your-email speed.
40% recall, 30% calibration, 30% explain-back, broken out by subject each week.
Add these as Learn subjects and Brainback treats every problem inside them as academic — everything else goes to Efficiency mode. Every subject below has its own dedicated page with topics, common mistakes, and hint examples.
Limits, rates, and shapes of change — earned, not delivered.
Vectors are directions, not numbers.
Balance the equation. In the right order.
Reason about the algorithm before you type it.
Model, assumptions, then math.
Draw the free-body diagram. Actually draw it.
Your voice, sharpened.
Recommended plan: Student — $9.99/mo or $59/yr. Undergrad coursework hits the free-tier caps by mid-week. Yearly saves $60. See all plans →
We say no to some prospects. Better to be honest here than to have you sign up and churn in week two.
The week my Brain score dipped, I already knew which unit it was. That used to be a midterm surprise.
Not unless you tell them. Brainback is academic-integrity-compatible on nearly every college honor code — it refuses to give final answers, which is the line most codes draw.
Check your course policy. In most cases, tools that don't produce final answers are permitted; tools that do (ChatGPT, Chegg) are not. Brainback is squarely in the first category — but the specific instructor rules for your class are the source of truth.
The Learn workflow is designed for the group case: everyone attempts in Learn mode individually, then compares approaches in the group chat. 'Here's my attempt' vs. 'here's the answer' is the culture shift.
Free covers a light schedule (~2 STEM classes). A full 4-5 class semester with heavy problem sets typically hits the free-tier caps by Wednesday. Student ($9.99/mo) removes them; Exam Sprint ($24.99 one-time) unlocks unlimited for 6 weeks if you're just cramming for a finals block.
Add it manually in Settings — you can attach a syllabus PDF and Brainback will treat it as academic. It works with any coursework you can describe; the pre-listed subjects are shortcuts, not limits.
The lines between stages are messy. If more of the day-in-the-life above sounds like someone else, follow the link.
