The dreaded course is going better than expected; but only slightly. I still have difficulty remembering all the rules; but I've found a strategy for remembering some of them. After I study a new lesson, I retake the practice quizzes from the previous lessons to make sure I cement the information in my brain. As the lessons are quite short, I'm considering rereading again from the start after each lesson so I can remember more. I wish my brain could retain this information more easily.
