There are two possibilities to set your students' levels.
When you create a new class, you might want to set a default start level for all students. You can do this via Teach > Course settings. On this page, you can edit the default settings for your classes such as the availabilty of the Level Assessment Test (LAT), automatic level adjustment, the pass mark and the default start level.
NB. Once students have been working with Holmwood's, their accounts will not respond to class level changes anymore!
If you want to change the levels of one or more individual students after they have started working with Holmwood's, you can do this by clicking 'Change students' current level' on the course settings page. Select the class(es) and student(s), choose their levels and click 'Submit'. You can select multiple classes and students.
