My number was 5xx and got first call at Nov 2018 for pre employ, and call for second pre employ again at April 5 2019, then got call for medical after a week and start training 3 days after medical. And for Apr 15 , 2019 training class start at about 70 student so I guess they called 100 people. And so far for day 7, about 33 passed, another 12 pass on day9. And the next class start next Monday 4/29
That's all I know hope that help, for your list number really no idea how much longer but wish you luck!
