ATA
I went to ATA last year. All in all I was reasonably happy with the service. All the instructors did their best to get the latest updates from a variety of sources including former students. Sure, some subjects could have been done better but I passed them first go so I was happy.
Usually start at 8.30 and was finished by 3-4 ish depending. Fridays were usually an early go because most like to get away. ie didn't worry about lunch time.
For module one, expect to be doing 2-3 hours a night and work on weekends. Module two, expect 3-4 hours + weekends.
