It is not possible to switch between online and in-house courses during a course level. We guarantee a maximum of [teilnehmer-max] participants in a course, so we need to know which course format you would like to attend at the time of booking. However, after each course level you are free to choose whether to continue learning online or in-house.
Example:
You can do A1.1. in-house but A1.2. then online (or vice versa).
