Can I simply take the test if another applicant forwards me the invitation and the link?

No, you may only take part in the test if you have received an invitation yourself.

You will receive an invitation email for the next possible test date, as soon as your application incl. all documents has been received and the BSc AT Admissions Committee has checked the relevant documents.

Please refrain from inquiries and wait patiently for updates. Everyone involved does what they can to process applications.
