1.5 years late to the game, but my daughter just finished one semester of AOPS' online honors 4th grade language arts class. I have to say, despite the high price ticket, the course is very impressive! Moreover, my daughter, and (from the sounds of it) most of her classmates, thoroughly enjoyed the course and want more! That said, the course is quite advanced and rigorous for the grade level AOPS pegged it at. The class projects were 1) A subtly persuasive play and 2) a time travel livestream of a historical research topic (they got to choose from three options and research material was provided). My husband and I both went through public school systems (my daughter is homeschooled and advanced in both reading and language arts according to assessment tests) and we were a bit awed by the writing projects. I would place the writing projects at middle school level. There's quite a bit of reading involved as well. Reading comprehension is through online quizzes. Vocabulary and advanced grammar concepts are interwoven into the reading comprehension quizzes and the writing projects. The classes seem engaging and fun (I did not watch the meeting recordings but my daughter always reported that the classes were fun)! I felt the homework load was kind of heavy for a supplemental class (as the course does not replace your child's regular language arts curriculum), but my daughter did all of her work without much complaint and says she learned a lot from the class and wants to continue taking AOPS language arts classes in the future, so that in and of itself is sufficient endorsement of the class for me!
