Hey, my name is jorge, im 18 and im from aguascalientes, well about if the education here is comparable with the education there... uhm... i guess it is, well i think it depends of the school. And ya, here it is bilingual schools, actually my mom is an english teacher and worked in a school called real del sur which is bi-lingual but its not the only one, it might be others, u can find them out i guess on internet or when u already be in mexico u can find out schools in a "yellow section" ("seccion amarilla") there u can find schools, hospitals, everything u want, its like a directory. One of neighbors could borrow it to ya. about costs? it depends of the school.
I hope to be helpful
good luck and welcome mexico.
