When you take a Renewal/Fast Track (Blended Learning) BLS training, you must do online training before your scheduled skills session.  Take your time learning the classroom material online, starting and stopping the program as needed. The entire in-person skills session is devoted to skills practice and questions (this takes anywhere from 30 to 45 minutes). Once you complete the online and in-person skills session components, you will be issued a digital certification card for two years.
