Set a paper. Share one link. Mark their working live.
Your students write on the paper with an Apple Pencil or any stylus, just like on paper. They submit question by question, you mark with a red pen, and they keep everything as a PDF.
Free. No passwords, and no student accounts. Everything is deleted after 24 hours.
Why online teachers like it
It is built for one-to-one lessons and small online classes, where you can't walk round the room and look over shoulders.
See the working, not just the answer
Students write by hand, so you see every step: where the method went wrong, not only that it did.
One link, nothing to install
Paste the link into Zoom, Teams, WhatsApp or your LMS. Students open it in the browser. No app, no account, no email address.
Mark as they go
Each question appears on your screen as soon as it is submitted. Tick, correct and comment while the lesson is still running.
Fresh IB-style papers in seconds
Pick the course (AA or AI), level, topics and paper style. Questions are original DarTutors work written to the IB syllabus, and a mark scheme comes with every paper.
Students keep a full record
One tap downloads a PDF of the paper with their working, your pen marks, the marks per question and your comments: ready for revision.
Private by design
We store only your email, to sign you in. The paper, the link and all student work are deleted 24 hours after you create the assignment.
How it works
About two minutes to set up, the first time.
You, the teacher
Sign in with your email
Go to Teacher sign in and enter your email. We send a 6-digit code from no-reply@dartutors.com. Type it in, and you're in. There's no password to remember.
Build a paper
In the paper generator, choose the course, level, topics, number of questions and paper style, as you would for a PDF.
Press “Assign online”
The button appears next to Generate once you're signed in. After about half a minute you get a student link and your marking page.
Share the link
Send the same link to every student. Each device that opens it gets its own copy, labelled Student 1, Student 2 and so on. Rename them to real names on your marking page if you like. Students never see those names.
Mark the work
Open a submitted question to see the student's working next to the mark scheme. Write on it with the red or green pen, enter the marks, add a comment and press Save. The student sees it within a few seconds.
Your students
Open the link
On an iPad, a tablet or a laptop. They don't sign up or give any details.
Write the working
Write on the paper with an Apple Pencil or stylus. There's a pen in three colours, a highlighter, an eraser and undo, and a resting palm is ignored. No stylus? Students can turn on Finger draw.
Submit each question
Press Submit under a question when it's done. It goes to you straight away, and they carry on with the next one.
See your feedback
Your pen marks appear on their page, with the marks and your comment underneath.
Download the PDF
Before the 24 hours are up, students tap Download my PDF to keep their paper, working, marks and comments.
Tips for a smooth lesson
- Remind students to download their PDF at the end of the lesson. After 24 hours it's deleted, and we can't recover it.
- Ask students to use the same device and browser throughout. That's how their copy is recognised, without any login.
- Rename each copy to the student's name as soon as they join. It makes marking a group much quicker.
- For a timed test, share the link when you say “start”, and watch the questions come in on your marking page.
- Download the mark scheme PDF from your marking page if you want it beside you while you teach.
Questions teachers ask
Does it cost anything?
No. Online assignments are free to use.
Do my students need an account or an email address?
No. They only need the link. We trust that you shared it with the right students.
Which devices work best?
An iPad with an Apple Pencil gives the most natural writing, and Android tablets with a stylus work too. On a laptop, students can write with a mouse or trackpad. Any up-to-date browser is fine.
Can students see the mark scheme?
No. Only you see the mark scheme, on your marking page.
What exactly do you keep, and for how long?
Your email address, so you can sign in. The paper, the student link, every student's working, and your marks and comments are all deleted automatically 24 hours after you create the assignment. You can also delete an assignment earlier yourself.
Are the questions taken from real IB papers?
No. Every question is original DarTutors work, written to the IB Mathematics AA and AI syllabuses.
