Hello, I'm a avid learner on Khan academy, and I have been learning on it for around 2 or 3 years. I noticed that the courses here are quite nice (AP physics, Chemistry, Calculus, and stuff), however there aren't many courses for the English and language arts section. I'm proposing a course:AP Language and AP literature, this would be really good for the more advanced learners. (because the grammar area with nouns, verbs, syntax etc is good however I think it only covers up to 10th grade). Thank you for your time
