During the modules of the Delft Method, you can stop any moment, but you will not get a refund. As you pay per Module, you’ll never lose much money. You can restart later, as Modules start every month.
During the longer courses you can stop after the first month without any problem. In case you want to quit later, you will have to pay the full course. However, you can postpone your participation in the rest of the course once.
You will not get a refund for a paid Delft Method Module, but you can postpone your starting moment once.
You will not get a refund of the deposit for a longer course, but you can postpone your starting moment of the course once.
