Hi! First of all you must have a vatsim account, if you do not get started at here
You must be associated to Portugal vACC, if you are not do so by sending an email to firstname.lastname@example.org saying "Please associate my VATSIM account to Portugal vACC to get started as an ATC!"
Once that is completed send an email to email@example.com requesting the theoretical exam for the S1 (Ground/Delivery) rating.
You have 30 days to perform the exam after starting it! If sucessfully completed email again firstname.lastname@example.org to get started in training! You will be placed in waiting list for an available mentor
