About onSET Prep and our editorial policy
onSET Prep is an independent learning resource for the C-Test format. It is not the official onSET and is not provided or endorsed by the TestDaF-Institut, g.a.s.t. or DAAD.
Responsibility for the content
Articles are published under the onSET Prep organization name. We do not currently list a named specialist reviewer or claim institutional accreditation.
Sources and practice material
- Statements about test format and scoring link to official onSET sources. Check application and admission requirements with the specific university or scholarship program.
- Our exercises and explanations are learning material, not official exam questions. Practice scores are not psychometrically calibrated and do not predict a CEFR level.
- A 14-day plan organizes available study time. It does not promise a proficiency-level jump or a particular test result.
- Publication and modification dates belong to each article. Substantive corrections update the modification date.
