A lot of people bull**** the extra curriculars. I've seen people say they know languages they don't even know a word of. As long as you can cover your tracks, you will get away with it 99% of the time. It is very dishonest but practically every personal statement is a begging letter full of overinflated crap.
You could say you know Spanish conversationally, you play Tennis, play Bridge, how are they going to check it. The system is broken and people lie, what can you do.
