Run a lesson with printed cards
Open Classroom Mode on the projector, pair your phone as the camera, add students and questions, then scan the room each question.
You need two devices and your students’ printed cards (print answer cards): a laptop or desktop as the display (connected to the projector or a large TV, if you have one), and a phone or tablet as the camera that scans the cards.
Open it on the projector
On the laptop or desktop (connected to the projector, if you use one), go to quizzy.earth/study/classroom. Under This device is, choose Display. No sign-in is needed.
Join with your phone
Scan the QR code under Camera access with your phone. Or open the same page on your phone, choose Camera, and type the six letters shown on the screen. The phone joins as soon as the sixth letter is in.
Add your students
On the projector computer, click Add students, then Add manually to type names one at a time, or Upload a file to bring in a CSV, Excel or text list from your register. You’ll see a preview before anything is added. To use the same list next lesson, save a class.
Add questions
Pick a quiz from Saved quizzes, or click Add questions to write or import new ones. Cards can only answer single-answer multiple-choice questions with up to four options. Any others are skipped, and the screen says how many.
Start the quiz
Click Start the quiz. After a short countdown, the first question appears on the projector. If something is missing, Ready to start? opens with a checklist: Students and Questions, which the quiz needs, then Cards and Topic, which are optional. A tick marks each one that’s done, and the button beside the rest fixes it: Add, Open when everyone is marked absent, Check to say your students have their cards or to print them, and Set to choose a topic. Start the quiz appears once students and questions are in. The checklist opens the first time you start with a class on a computer, because Quizzy doesn’t know yet whether your students have their cards. It doesn’t open for that again unless you add students who don’t have a card yet, or at all if you printed the cards on this computer. If a student lost their card or left it at home, click the printer icon at the top of the screen during the lesson to print the cards again (on a phone, it’s Print cards in the settings menu), without stopping the quiz.
Scan the room
Students hold up their cards with their answer at the top. Sweep your phone slowly across the room. Every card in view is read at once, so there’s no need to stop on each one. The list under the camera shows who’s still to scan. Tap a name to record their answer by eye. When you have them all, tap Done. The classroom and students in the video below are AI-generated. The phone shows Quizzy’s real camera screen with sample names.
Use the full-screen camera (optional)
For a bigger view of the room, tap the full-screen button in the corner of the camera. Turn your phone sideways to see more of the class. The button in the bottom corner shows how many students are left. Tap it to open the class list, and tap ⇄ in the list to move it to the other side. To leave, tap Exit full screen in the top corner. When you tap Done, the phone leaves full screen to show the results, and Next question brings it back. If your phone asks for permission, see full screen and motion access.
Reveal and move on
The correct answer shows on the projector. If a card was misread or turned late, tap the student’s name to change their answer. You can do this until you move on. If you added an explanation, tap Show explanation on your phone, and Hide explanation to go back to the answer. Then tap Next question.
See results
After the last question, tap See results. The projector shows “Lesson complete”, with no scores on the wall. You can email each student’s answers to yourself in the next step: see class reports.
Email me the report
On your phone, tap Email me the report. Enter your email address and tap Send report. The report arrives as a CSV file with each student’s answer to each question.
