NoValueAviator pretty much summed up most of my experience.
PSIs were mediocre at best. The line guys were great.
Group study at the hotel and pick the brains of any upgrades there as well.
Read, read, read about systems and the FMS.
Stay after hours at the schoolhouse to use the computers and IPT. It's usually quieter too.The downstairs room at the hotel can get busy and sometimes distracting. Lots of storytelling and socializing during evenings.
Come in with a positive attitude you'll make it. Hell I did!!
