Can I change my personal details after registering for the dMAT?
Not directly. Changes to personal data require agreement with g.a.s.t. rather than a self-service edit in the portal. Deregistration is possible only through the participant portal before the deadline, with a refund minus up to a 15 percent fee. Email kontakt@gast.de as soon as you spot an error.
You cannot simply log in and edit your personal details once you have registered for the dMAT. Any change to your personal data requires direct agreement with g.a.s.t., so the moment you spot an error, your first move should be an email, not a portal search for an edit button.
What You Can and Cannot Change Yourself
| Situation | What You Can Do |
|---|---|
| Personal data error after registering | Contact g.a.s.t. directly, this is not a self-service edit |
| Want to cancel before the registration deadline | Deregister via the participant portal, refund minus up to 15 percent admin fee |
| Want to cancel after the deadline or you miss the exam | No refund available |
What to Do the Moment You Spot an Error
- Email kontakt@gast.de immediately, describing exactly what needs correcting.
- Attach or reference your passport details so g.a.s.t. can verify the correct spelling.
- Do not wait until closer to the exam date, since data corrections take time to process.

My Advice
Treat any error in your registration as urgent, not something to fix later. Email g.a.s.t. the same day you notice it, and keep a copy of that email in your application folder, so you have a paper trail if the correction takes a few exchanges to confirm.
