Enjoyable! – Test your Vocabulary with Science XL Review

Enjoyable, but I also would like more feedback. How many times can I test? What do the results mean? For example I scored very high in English, yet even higher in Spanish, and Spanish I acquired only later in life. Does this mean Spanish is more regular in its structure than English and therefore divergence from the norm is more easily noticed? I assume this is so. What does the data prove?
