Translation of shredded in German

So by age twelve, I had decided that I wanted to learn English and I was studying for the United States TOEFL at age twenty. Being bilingual practically from birth, makes speaking languages very easy for me.
In order to quickly become successful, one would have to change certain points, at least in my opinion: After 5 months of learning, I have still not found the grammar practice on which I should concentrate.
My morning was great. How was your weekend? In order to learn the language to a high level I figure you need two or three years. I was in Malaga last summer for a few days and studied a lot.
