More MySQL rows

Hey For School I have to centralize my colleagues' absences I've been thinking about using the databases. I creates a html form and a table in phpMyAdmin, for school subjects I use Checkboxes as you can see in the image, but if I select 2 subjects in the database I have only one register with first subject which I selected first. Can you give me a MySQL query to register twice with same name but different subjects like:

William:English:unmotivated absence
