As others have pointed, you should expect nothing... More than classes, there are teachers, and the same class can be real different depending on the teacher...
Another factor is the duration of the classes... Of course longer classes can hold deeper contents both from theory and practice points of view... The first time I took classes I had already been a hobbyist, and those classes (once a week) did last for six months: I learned lots of things.
After some more years of shooting, I started to see how complex and detailed different fields in photography were, and even after having sold a few photographs both to customers and magazines, I decided I wanted to study photography in a more serious way... The place I decided to study at, had three options or plans: the introductory course: one year, three weekly classes... The basic course: three years, three daily classes three days a week (9 per week)... The career, six years with 3 daily classes 5 days a week (15 per week)... I went for the career... I remember we were several hundreds of students from all around the world during the first year (in several groups of near 40 students each), and year after year less than 50% of us could continue to the next year because of a very high academic and aesthetic exigence... Every year, only a few people, maybe less than 10, end the career... I saw most people start studying photography with a too relaxed attitude... This beautiful craft requires precision and experience from light understanding and metering to optics and mechanics to chemistry to perception to communication to aesthetics to lyricism... I have met good photographers who never cursed a career, but all those I've met, were very exigent with themselves, and very disciplined and hard working... If photography was not that complex, the world would be full of lots of wonderful young photographers, and that's not the common case... I'd encourage anyone planning to study photography... History of photography, and visual narrative, are a lot more important and interesting than basic technical concepts and skills...
