Auto-grade multiple-choice and short-answer homework,
with wrong-answer tracking and parent report links
AGA-Lite grades instantly the moment a student submits an answer to a multiple-choice or short-answer question, lets them retry right away on a wrong answer, and shows the explanation as soon as they get it right. Results and wrong answers are collected per student, and a parent report covering accuracy and weak units is shared by the teacher, who issues a link and sends it to parents directly.
AGA-Lite is free to start for 2 months
No payment or card required to sign up. The conditions below (student count, duration) may change as the service evolves.
Multiple-choice and short-answer auto-grading + parent report links
Student cap and free period may change. We notify the director by email and in-app 14 days and 3 days before the free period ends, and nothing turns paid unless you apply. After it ends, registering new problems and students is restricted, assigning homework stays possible for 7 more days, and existing records and student submissions continue. When you switch to paid, your classes, students, and problems carry over as they are. See pricing.

AGA-Lite paid tier
You pay only for the students you enroll (no rounding up to blocks of 50). Each month we confirm next month's seat count from your enrolled students on a cutoff day you choose. The launch price is locked for 24 months from the date you convert to paid, if you convert by June 30, 2027 (academies already on the paid plan included). After that period the list price (1,500 KRW per student / month) applies from the next usage month, and we notify you by email and in-app 30 days in advance. A minimum monthly fee of 10,000 KRW per academy applies (VAT excluded; 11,000 KRW incl. VAT) — if students × unit price (plus any overage) comes to less, you are billed the minimum. Prices exclude 10% VAT (e.g. 50,000 KRW + VAT 5,000 KRW = 55,000 KRW). VAT-exclusive billing applies from November 2026 usage under the revised Terms of Service (effective Oct 30, 2026). The list/launch price split and the minimum fee apply from December 2026 usage under the revised Terms of Service (effective November 2, 2026); earlier usage is 1,000 KRW per student with no minimum. There is no card auto-pay — the director applies in the app, and the account converts to paid once payment is confirmed (bank transfer with an e-tax invoice or cash receipt; card payment coming soon).
Examples (monthly, excluding add-ons, VAT excluded → incl. VAT):· 50 students: launch 50,000 KRW → 55,000 KRW / list 75,000 KRW → 82,500 KRW· 100 students: launch 100,000 KRW → 110,000 KRW / list 150,000 KRW → 165,000 KRW· 150 students: launch 150,000 KRW → 165,000 KRW / list 225,000 KRW → 247,500 KRW· 200 students: launch 200,000 KRW → 220,000 KRW / list 300,000 KRW → 330,000 KRW· 300 students: launch 300,000 KRW → 330,000 KRW / list 450,000 KRW → 495,000 KRW· 500 students: launch 500,000 KRW → 550,000 KRW / list 750,000 KRW → 825,000 KRW
- Everything in the free tier, unchanged — multiple-choice and short-answer auto-grading, parent report links, and more
- No free-tier student cap (50) — sized to your academy
- Detailed parent reports (per-question solve-time delay highlights, recent learning history, and more — see example below)
- Detailed statistics for teachers — class-wide accuracy, solve time, retries, and late submissions in one exportable file (see example)
Refer another academy, get billing credit back
When an AGA-Lite academy director refers another academy and that academy starts paying, both academies benefit.
- Referring academy — while the referred academy keeps paying, you earn a monthly credit based on its usage, deducted from your own monthly fee (subject to a cap relative to your fee and a limited period).
- Referred academy — a discount on its first paid month.
- Entering the code — directors find their academy's referral code under "Academy settings" in the teacher app; the referred academy enters it on the sign-up screen. Academies that signed up without a code can enter one once in Academy settings within a set period after sign-up, before their first payment.
- Only the first code recorded for an academy applies; self-referrals and referrals between academies of the same director are excluded.
Credit and discount rates, eligibility, and duration may change under our operating policy. For details, email support@ssamm-ai.com.
Basic reports are free, detailed reports are paid
Reports are compiled automatically every week on both tiers; teachers issue a link and share it with parents themselves (automatic sending is planned for January 2027). What differs is how much detail is included. The example below uses the same student on both sides.
Jiwon's multiple-choice homework status
Per-question solve time and recent learning history are in the detailed (paid) report.
Jiwon's multiple-choice homework status
- Applying trigonometric functions — wrong 2 times in a row (9/2, 9/3)
- Exponents & logarithms — correct 3 times in a row (9/1)
- Applying trigonometric functions — wrong on first attempt (8/29)

Grading and parent communication, handled together
Automating multiple-choice and short-answer homework surfaces per-question solve time and weak areas at a glance, and makes parent communication effortless.
Parent report links
Accuracy, problems solved, week-over-week change, and units still being retried — compiled automatically every week. Teachers issue a link in the app and send it themselves (text, messenger, etc.); parents open it with no login.
4-week trend and weak-unit comparison are already included for free. Paid adds slow-question highlighting and a recent-learning- history timeline. (See comparison above)
Wrong-answer tracking & retries
Students can resubmit after a wrong answer, and every attempt is logged so teachers can track progress per student.
Submission status & grade stats
See at a glance who has and hasn't turned in homework in each class, and view class and student grade statistics in the app. Downloading the detailed statistics Excel with charts is a paid feature, also available during the free trial.
Your own problem bank
Every problem you register stays your personal property — searchable, filterable by difficulty, and reusable next semester or in another class.
Reusable homework sets
+ Excel / PPTX bulk import
Save a 20-question set once and reassign it to any class or semester. For many problems at once, fill in answers and units in the Excel template and upload the images with it, or import a PPTX file.
Per-student shuffled printing
Print the same worksheet with a different question order for each student, discouraging copying from a neighbor.
Short-answer auto-grading
Assign questions where students type a number or a short answer — no choices needed — and they are graded the moment they are submitted. Equivalent answers such as 3/4 and 0.75 are both accepted.
Item analysis
See how often each choice was picked for every question, with the most popular wrong choice highlighted, so you can spot misconceptions at a glance.
Homework analysis
Every homework automatically points out the hardest questions, the ones that took students unusually long, and answer keys worth double-checking. Each student's missed questions are listed, so you can send a follow-up assignment to just those students in a click.
Achievement by unit and keyword
Combine results across classes and homework to see where your students are strong and where they get stuck, by unit or keyword — with weekly trends, class-by-class comparison, and an Excel download.
Lite Paid · also during the free trialDetailed statistics Excel with charts
Submission status, correctness, score, solve time, retries, and late submissions for the whole class, per student × problem, with auto-generated charts — downloadable anytime, plus automatic monthly snapshots. (See example)
Included in Lite Paid & Full · also during the free trialStudent report cards (PDF)
Pick a period and homework, then download a PDF report card for each student (as one file or a per-student ZIP): scores per homework, accuracy by unit, and a note from the teacher — ready for parent conferences. The comparison with the class average appears on the paid plan only, and problem content (questions, choices, answers) is never included.
Included in Lite Paid & Full · also during the free trialFrom submitting to retrying, everything is instant
Instead of waiting days for a batch of graded results, students see feedback the moment they submit and can retry right away.
Real-time grading
Results appear the instant an answer is submitted — no waiting on a teacher or TA.
Exam mode — no instant grading
When you don't want results shown right away, flip one option when assigning homework. Students submit and move straight to the next question (a banner reminds them grading isn't real-time), and results are revealed all at once once the teacher confirms or everyone finishes. Works for both multiple-choice and short-answer problems.
Solve-time tracking
Time spent per question is logged automatically (teachers can turn this off per class), surfacing struggles that a plain right/wrong count would miss.
Retry on wrong answers
A wrong answer isn't the end — students can retry, and every attempt is kept as a learning record.
Explanation on success
Getting it right reveals the explanation immediately, turning grading into learning.
Pause and resume
Homework assigned as a multi-problem set can be paused anytime — progress is saved on the server, so logging out or switching phones doesn't lose a thing. Next login picks up exactly where the student left off.
AI-generated retry problems (add-on)
When a student gets a multiple-choice problem wrong, the result screen offers "Try a similar problem" — a new problem on the same concept. Instead of memorizing the same problem, it is a second check that they actually understood it. AI prepares similar problems for each problem in advance, and only those the authoring teacher has reviewed and approved are ever shown to students. It currently applies to multiple-choice problems and is designed around math.
This is an optional add-on on top of the paid plan (not included by default). Pricing is not final and is arranged case by case — contact us with any questions.
Add-on · pricing not finalRegister the problems you already own —
they remain your intellectual property
Use the multiple-choice and short-answer problems and answers you already have.
Teacher registers problems and answers
In any subject, register with just a one-line answer key (e.g. 31425) and a photo of the test sheet, or import in bulk from Excel/PPTX — then assign it to a class right away.
Student submits an answer
Students check assigned homework and pick a choice or type a short answer.
Instant auto-grading
Graded immediately against the answer key; wrong answers prompt a retry.
Share a report link with parents
The teacher issues a link to a summary of accuracy and weak units and shares it with parents.
Common questions before signing up
Who owns the copyright to registered problems and answers?
Problems, answers, and explanations a teacher registers belong to that teacher. The director and other teachers in the same academy cannot see the problem content — only results and statistics are shared. When a teacher leaves, their problems pass to a successor only with that teacher's own consent. We don't scan copyrighted workbooks into a shared, searchable problem bank; academies use the problems they already own, scoped to the teacher who registered them.
How is student data protected?
Student data is separated per academy — no other academy can access it — and stored on servers in Korea (Seoul region). Traffic is encrypted, passwords are stored as irreversible hashes, and data is processed only under academy-parent consent. Data of withdrawn students is automatically deleted after 6 months, and a cancelled academy's data after 30 days. Parent reports require no login — they're viewed via a link, so no account credentials are ever exposed, and the link becomes invalid immediately when a student is withdrawn.
Will I be auto-charged when the free period ends?
No — there's no card registration and no auto-pay. The account converts to paid only after the director applies in the app and payment is confirmed; if you don't apply, nothing turns paid. After the free period, existing records and student submissions continue — only registering new problems and students is restricted.
Can grading ever be wrong?
Lite's grading is not an AI judgment: it compares the student's answer with the answer key you registered (short answers by defined comparison rules), so there's no grading error. If the answer key itself had a mistake, fixing the problem instantly regrades submissions already made against the new key, and any changed results are recorded.
What devices can students use?
Android and iOS apps and a web version are on the way. Students enter the academy code to request to join a class, and the teacher approves it.
What if a student attends multiple academies?
One account is tied to one academy. Joining multiple classes within the same academy just needs a join request in the app; a different academy using SSAMM requires a separate account.
Can I share my problems with another teacher?
Problems aren't shared automatically. You can export a problem as a password-protected file for another teacher to import — once imported, it becomes fully their own problem.
Google Forms can grade multiple-choice too — what's different?
The difference is that the whole academy workflow is connected, not just grading: assignment by class and student, missing-submission checks and reminders, retries and attempt history for students who got it wrong, explanations after a correct answer, homework from a one-line answer key, reusable problem banks and homework sets, plus parent reports and per-class/per-student statistics that build up automatically.
Can I move the problems I already use?
Yes. If you have paper test sheets and answer keys, type the answers in one line and upload a photo or PDF of the test sheet; problems already organized in files can be moved all at once via Excel or PPTX. You can also use the AI prompt in the app to produce a file in the import format (always check AI-generated answers yourself). Problems you register remain your property.
Can I use subjects other than math?
Yes — any problem that can be written as multiple-choice or short-answer works the same way, in any subject: English, Korean, science, social studies, and more. A student can also attend several classes in the same academy (e.g. math + English).
