How impressive of an EC is learning Chinese to near-fluency?

I’ve spent an average of 20-30 hours a week, every week for about the past two years, learning Mandarin Chinese (as someone with no cultural/ethnic connection to the language).

Now coming into my senior year, I only read books, watch shows, and listen to content in the language. I’ve also used my proficiency as a base to write paid and free articles about language learning and co-found a leading resource (~10k monthly visits) for learners at the intermediate+ stage. This fall I’ll be taking and hopefully passing the highest level of a proficiency test of Chinese for foreign speakers.

This is something I’ve put a lot of time and effort into, but there are obviously other applicants who are fluent a decade ahead of me just because of their family background. Additionally, I’ve been taking (beginner’s, the only level available) Chinese at school for about a year. Is my EC still something of a ‘spike’ despite those factors?

As a final note, plan to apply for CS to some of the more competitive unis, but believe this EC shows well-roundedness at the least, though it is not directly related to my planned major.
