Qt Essentials Certification
Please I need to know how much it costs to get certifcation for Qt Essentials
Hi @petrong, and welcome :)
I believe the cost will depend on your location (or more specifically, the location of the test centre you decide to attend).
The exams are organized by authorized PearsonVUE test centers. Please find more information on test centers near you from here.
So I suggest you sign up for an account at PearsonVUE, and follow the links to schedule an exam (if I remember correctly, you have to go that far to see the prices on their website), or contact PearsonVUE and ask them directly.
