Answer:
Most of the English questions I've encountered in K12 online school are about book readings. Which might seem hard however, I've noticed a pattern in most of thee quizzes, although all the questions are different they do follow the same patterns the last question. So say you got the wrong answer on a quiz just bring up the review and read the correct answer, although the new question won't be the same it will most likely be similar.
hope this helps :)
