Correção de texto: I'm studying

Today I've been studying the adjectives for 1 hour. In the last week I studied the tenses, perhaps in the next week I will study all tenses again. I study many things in a day, at afternoom study english and programming, sometimes in afternoon I study music, in sunrise I go to University. I like to listen to bbc radio in my phone and watch movies to improve my skills.
I have a big dificult with words and expressions because I have many codes and math formulas to learn.
