Hi Sanjukta,

There are no voucher codes available for Mendix certification exams unless you have registered for a training by an official Mendix training partner and they have sent you a voucher after completion of the training.

You can go to https://academy.mendix.com/link/certifications/6/advanced to register for the Advanced certification exam. It's on demand, so you can take it whenever (within 30 days after registering) works best for you.

Best of luck with the exam!
