Cool, me too, from wich part of Mex.?
You need to get the First Aid, Dental decks and questions like ASDA but I will say dental decks and ASDA question everybody recommend it the most.
You will need to JCNDE and apply for all the requirements to register for the NBDE 1
Get ready with your Kardex, certificate, cédula, and other things that I do not remember well, but you will send it to the ECE to check your credimentials, after that they will give you a DENTPIN and there you will pay foe your test and schedule.
