Dear Vicky, I apologize for the inconvenience. Please Note that my summaries are not a complete summary of the textbook, it's only a summary of what I had to learn in Grade 9 during the lockdown. I am currently writing exams as soon as I can get time off I will update all my summaries to your requirements.Best wishes Anika du Toit.
