The English subject is probably one of the hardest subjects for me when I was in school. It was too complex for me to learn the structure and details on how to properly construct sentences and also how to use words correctly. For me, I don't think it was really necessary to teach us this subject on a deeper level. It was even present in my college days in which I remember I probably had around 3-4 English subjects. Although I agree that it does help us become more fluent, I just don't think it was imperative to learn a lot of it. Also, to be honest, I'm pretty sure I learned about the English language more on experience by watching a lot American TV shows and movies.
How about you? Was your experience in school also the same as me? Did you have lots of English subjects? or did it only have a few of them. Where did you primarily learn the language?
