Translation of smarty in Spanish

I remember that after highschool I went to study English in New York. First I did not know whether the city was right for me cause I wanted a place where I would not feel lost. However, it was the right choice.
The words will mostly be easy. I would prefer full sentences and not just short clauses with the article, the noun and an adverb/adjective. Do you think you could do 1000 sentences per working day? This way we could finish quickly.
Maybe it's just a small mistake but I think that we corrected almost all errors. But I'm not worried anyway, because you already have good language skills. Good luck with your exams tomorrow.
