My school nor any in my city offer AP courses, but there is something else. Will it still count?

I'm a Canadian grade 11 student and literally no schools in my area offer ap classes, however my school is the biggest in the city and we uniquely have "enriched" classes that are a higher difficulty than the academic level. Apparently at my school, if you continue with enriched classes, you can take the related AP exam in senior year. There aren't many options though, only AP bio, physics, English, and French. I only plan on writing ap physics at school, but I also want to write ap chem and calculus ab. Is it possible to write them outside of school? And does what I have here still work when applying to top schools?
