After the BLS/AED competence testing, both groups will continue the rest of their first aid course together and the first part of the study ends. Three months later, the investigators will repeat the same scenario over the same time interval and record the same parameters. At the end of the second testing, a short feedback will be provided on the BLS/AED competence and further practice will be provided to the students to improve their CPR competence. From this point forward no further data will be collected.
