Join a class as a student
Using a Computer / Laptop
To use Classroom, you need to sign in on your computer and then join classes. Then, you can get work from your teacher and communicate with your classmates. When you join a class on one device, you're enrolled in that class on all devices.
Join a class with a class code (PC)
Go to classroom.google.com and click Sign In.
At the top, click Add Join class.
Enter the class code your teacher gave you and click Join.
A class code consists of 6 or 7 letters or numbers. For example, hjhmgrk or g5gdp1.
