This is our general PayPal payment functionality. You need to put in manually the indicated course/class/program fee (as on our web sites) or the by email agreed fee (always in EUR) to get access to the course/class/program you want to sign up for. After payment, you'll receive the necessary details by email. Access to the course/class/program is only granted if the applicable fee is paid in full.








No refunds possible since you get full access to the complete electronic course/class/program material (Videos, HTML, Jupyter Notebooks, Python codes, etc.). Also note that the course/class/program material is copyrighted and not allowed to be shared or distributed. It comes with no warranties or representations, to the extent permitted by applicable law.
