As a none native speaker (English would be my 3rd language at best, maybe 4th) I expected to dramatically underperform compared to most scores here, but: You said yes to 76% of the existing words. You said yes to 0% of the nonwords. This gives you a corrected score of 76% - 0% = 76%. Which I find oddly high.
