Jules,
When Jennifer says the classes are scheduled she does NOT mean filled. It looks like they wait until two to three weeks before the class date to actually schedule bodies to the classes.
I believe the main reason for this is they want to give the stop loss people an opportunity to get into the first class they are available for once released. When she says you are a May person, she is likely assuming that the Military guys/gals ahead of you will be released and available for class. By March her tune may very well change if the stop loss people are still tied up.
