Who is at risk?
See who has never practiced, who stopped, who is struggling with several topics and who has barely practiced. One click sends them a reminder.
For professors and universities
Know who in your class needs help before the exam.
Upload the material you already teach with. Your students practice with questions built from it, on their phone or computer. You see, by name, who is falling behind and which topic to teach again.
Free for one exam period. Nothing to install.
Today you don't find out who didn't understand until exam day.
You're flying blind
Between one exam and the next, there's no way to know who is studying, who stopped, or which topic the class got stuck on.
A good question bank costs you a weekend
Writing questions with believable wrong answers and an explanation for each one takes hours. That's why there's rarely anything to practice with.
Class time gets spread evenly
You review everything equally because you can't tell which topic they already understand and which one needs another explanation.
What you see
One screen. Three answers.
Open your group's progress whenever you want. It answers three questions with names and head counts, never with averages that hide who.
What aren't they getting?
The topics they struggle with most, in order, with the question to open class with. When one topic depends on another, it tells you which to review first.
Is it improving?
Compare the last 7 days with the 7 before: how many practiced, how many have a topic in red, and who improved, by name, so you can recognize them in class.
Not just which topic. Also how to teach it.
For every topic they struggle with, the panel shows the wrong answer most students choose and why it's wrong. You walk into class knowing which confusion to clear up.
- The question worth starting with.
- The most chosen wrong answer, with the reason.
- Which page of your material covers the topic.
And when you want the detail
The whole class at a glance
Every student against every topic, in color: mastered, doing well, halfway, struggling or not practiced.
Student by student
Open any student: how many questions they've answered, which ones they get right and when they last practiced.
Ask the panel
Type your question the way you'd ask a colleague. It answers with your group's data and, when it doesn't have the data, it says so.
Every Sunday, in your inbox
A summary of the week: how many practiced, who improved and what to teach again.
What your students get
They practice with your material. And every mistake teaches them something.
Questions from your class
They come from the material you uploaded and published, not from a generic question bank online.
Every mistake explains why
When they miss, they see right away why their answer is wrong and which one was right.
It adapts to each student
Adaptive Study asks more about what they struggle with and less about what they've already mastered.
Free and on their phone
They join with a link and practice from the browser on their phone or computer. Your group's material costs them nothing.

mediumAnnuities
A person makes a loan payment at the end of each month. How is that series of payments classified?
- AIt is an ordinary annuity, because each payment is made before the monthly period begins.
- BIt is an annuity due, because each payment is made at the start of the monthly period.
- CIt is an ordinary annuity, because each payment is made at the end of the monthly period.
- DIt is an annuity due, because each payment is made after the monthly period closes.
Incorrect
The classification depends on when the payment falls within the period, not on its being monthly. A payment at the end of the month makes it an ordinary annuity.

Adaptive Study
It's not a fixed quiz. Every answer decides the next question.
This is how your students practice. Adaptive Study keeps track of how each student is doing on each topic of your material, and uses that to choose what to ask next.
How often each topic comes up
A topic they struggle with
A topic they haven't practiced yet
A topic they half know
A topic they've mastered
More practice where they struggle most
The topics a student misses come up more often. The ones they've mastered come up less, but keep coming so they aren't forgotten.
How much they remember of a topic
Day 13714
Without practicing againPracticing on different days
An illustration of the calculation, not data from a class.
It goes back to what's fading
It estimates how much a student remembers of each topic from when they practiced it and how it went. When they come back to study, what is fading gets priority.
The difficulty of the questions
Annuities- 1easy
- 2easy
- 3medium
- 4medium
- 5hard
- 6medium
- Getting them right: harder ones come up
- A miss: they ease off a little
It raises the difficulty when they're ready
Each topic starts with mostly easy questions. As the student gets them right, harder ones come up, and after a miss they ease off a little. So they don't get stuck on the hard ones or stay on the easy ones.
Why each question comes up
- 1AnnuitiesStrugglingGoes first
- 2Compound interestHalfwaySwitches topic so it doesn't repeat
- 3AnnuitiesStrugglingComes back soon
- 4Perpetuities and amortization schedulesMasteredComes up rarely, just for review

It mixes the topics
It doesn't ask topics in blocks or in just any order: it alternates them based on how the student is doing in each one, and comes back sooner to the ones they struggle with most. Within each topic, it first asks what they haven't seen.
Why your panel only counts Adaptive Study
Because that's where students practice topic by topic and see the explanation right away. Every answer updates how they're doing on that topic, and that's what builds what you see: who is at risk, which topic is hard and who improved.
Counts
Adaptive Study
Practice with instant explanations. It's the only thing that moves your panel.
Doesn't count
Exam Simulator
A timed exam with random questions. Your students can use it to rehearse; the result doesn't move your panel.
You don't see it
What they study on their own
Their personal documents don't count and don't show up in your panel.
And for a topic to show as "Mastered", getting everything right in one afternoon isn't enough: the student has to get it right on different days.
Practicing with questions and spreading study over several days are the two study techniques that research rates highest. Adaptive Study is built around both.
What the research says
How much can your students improve?
We won't promise you a grade. What we can show you is what has been measured when students practice with questions instead of only rereading their notes.
One week later
Of every 100 ideas in a text, those who tested themselves recalled 56 and those who only reread it recalled 42.
University students, in a lab. After 5 minutes, those who reread remembered more; a week later it had reversed. Roediger and Karpicke, 2006.
In a real course
On the course exam, the same students got 84 of every 100 questions right on the concepts they had practiced with questions on different days, and 72 of every 100 on the ones they studied as usual.
An Introductory Psychology course, 79 students. A second experiment found a smaller gain. Rawson, Dunlosky and Sciartelli, 2013.
Fewer failing students
Of every 100 students, about 34 failed or dropped the course with lecture-only classes, and about 22 did when they also worked on questions and exercises in class.
An analysis of 225 studies in science, engineering and math (failure rates, in 67 of them). It measures active work during class. Freeman and colleagues, 2014.
Which techniques work
2 of 10study techniques rated high utility
Of 10 study techniques reviewed, only 2 were rated high utility: practice testing and spreading practice over time. Highlighting and rereading were rated low.
Dunlosky and colleagues, 2013.
And a review of 222 studies in real classrooms, with 48,478 students, found that class quizzing raises academic achievement to a medium extent (Yang and colleagues, 2021).
These results come from published research on the method (practicing with questions and spreading study over time), not on StudyBuddy, and they don't guarantee a grade. What happens in your class is what we measure together during the trial.

The free trial
Free for one exam period
We're opening the free trial to a small number of groups, 4 to 6 weeks long, to try it in a real class.
What's included
- Your professor account and your groups.
- The questions from your material, at no cost.
- Group progress, the chat and the Sunday summary.
- Free access for all your students.
- We help you get started, by email or video call.
What we ask in return
- That you use it with a real class for one exam period.
- That you tell us how it went at the end.
- If it helped, that we can share the story without student names.
Frequently asked questions
You can create your group, upload your first document and publish your first topic the same day. What does take time, and is worth it, is reviewing the questions before you publish them.
PDF, Word, PowerPoint and text files; class recordings in audio or video (up to about 3 hours); and YouTube videos that have captions.
It isn't required, but it's worth it. You can approve them one by one, edit them, discard them, or approve all the questions of a topic at once. When you publish a topic, anything you haven't reviewed goes out as is and anything you discarded stays out. Nothing reaches your students until you publish it.
No. They create a free account and join with your link from the browser on their phone or computer. Practicing with your group's material costs them nothing.
No. It's practice, not an exam. It doesn't give grades or decide who passes: it shows you who has practiced and which topics are hard, and you decide what to do.
The platform is in Spanish and English, and questions come out in the language of your material.
Each student creates an account with their name and email. You see their name, email and progress on your group's material. You don't see their personal documents or what they study on their own. They can leave the group whenever they want. The details are in the Privacy Policy.
There's no list price for professors or institutions yet. If you want to continue when it ends, we'll talk about it with your group's data in hand.
