As the first commenter said, there are different levels depending on your age and educational grade level. If you’re in elementary, then you’ll be in ንዑስ ክፍል; if in high school, አብይ; if in prep, ወጣት ክፍል. But the courses are more or less the same, except they get broader in content. Some of the courses given are ትምህርተ ሐይማኖት; የመፅሀፍ ቅዱስ ጥናት; የቤተክርስትያን ታሪክ; የመዝሙር ጥናት:: I guess their names are pretty self explanatory.
