study really hard ^^
no i didn't. i attended one of 14 national schools of Latvia (title is given if some 97% of schools students have levels of C,B,A)
and i never had to study english to get along. even now i have only simplistic understanding of all the times - present perfect, past continuous etc. you could say i've developed a kind of sense of how to use the language - what time is used when and things like that when i simply see the text. english classes - didn't attend half of them and never did my homework
teacher gave me 6 at the end of the 12th grade yet i scored at the very top at the exams.
