Sounds like the post-test was done separately to me.
Session 1 is probably about 2 hours of "training", with the rest of the time eaten up by the pretest and consent paperwork. Sessions 2 and 3 would be be almost entirely training (3 hrs each), which gets you to 8 hours of training in 3 sessions, leaving the last one for just the post-test.
