I was out by 1230p today. Here's why they call more people then they need. Reasons are people defer(because they live in Florida, or other parts of the state, isn't the right time for them etc...), fail drug test, get placed on medical hold(sleep apnea will have you on medical hold for 30 days if you have it and need to get the cpap. Machine etc...) lots of reasons they call so many extra candidates. They want to make sure they enough candidates to fill the classes.
