Before you begin: You need a Lena account with a school profile. See
Creating Your Account and School
Profiles if you’re new.
Joining with an entry code
Your teacher will give you an entry code — a short alphanumeric (letters and numbers) code unique to their course. Here’s how to use it:Go to the Courses tab
Open the Student App and tap the Courses tab at the bottom of the screen. You’ll see your list of enrolled courses (or an empty state if this is your first course).
Enter the entry code
Type the entry code your teacher gave you exactly as shown — codes are case-sensitive.

Why a code might not be needed
Some courses are set up so that students who match certain criteria (your faculty, department, level, grade, or class section) can join without an entry code. If the teacher configured student groups for the course, you may be able to register directly — the system checks whether your school profile matches the course requirements. If you try to join a course and it asks for an entry code, it means the teacher requires one. Ask your teacher for the code.Browsing your courses
All your enrolled courses appear in the Courses tab. Each course card shows:- Course name
- Teacher’s name
- School name

Viewing past courses
Courses from previous terms or semesters are saved in your Past Courses section. These are courses whose academic period has ended. To view past courses:- Go to the Courses tab
- Look for a Past Courses section or toggle
- Tap any past course to review its materials and your grades
You can still view study materials and your grades from past courses, but
you can no longer submit new work.
Leaving a course (unenrolling)
If you joined a course by mistake or no longer need to be enrolled:Go to course options
Look for the menu icon (three dots) or settings within the
course. A list of course options will appear.
Multiple schools
If you have profiles at multiple schools, make sure the correct school profile is active before joining a course. Each school profile has its own separate list of courses. To switch school profiles, tap your profile icon and select the school you want. See School Profiles for details.Troubleshooting
