When did your seatime start? Somebody correct me if I’m wrong on this, but I believe that made a difference on what assessments and requirements/STCW classes you had to fulfill.
Also, clarify on the fact that you got your National 3/M but not your STCW when you tested? If you didn’t request it when you did the National, I’m pretty sure that meant that those assessments and anything used to get credit for that National got wiped when you received the National ticket. (I think)
