https://ets.edu.pl ETS is an abbreviation that can carry different meanings, so I would first want to understand the educational context intended here. The name alone should not decide the subject for a reader. That is how I approach ETS educational information. Clear descriptions can show which questions the information helps answer and what background is useful. I like the moment when a compact label becomes connected to a specific purpose, because that makes it easier to explore without relying on an uncertain association.
