Hello Everyone! New here, and to the PTCB community. Recently was certified this past June. So for those wondering how the "at-home" testing experience is, let me tell you, there is nothing to worry about. PTCB makes sure your computer is compatible, and that you know exactly how the process will go. Just have a clean testing area, and no people in the house, and you are all set to go! If you have any other questions let me know, would be glad to help :D
