HelloDue to Corona, my classmates and I have unfortunately not had the opportunity to get the proper schooling to pass our exams. Therefore I would like to have both answers and explanations on how the answers were reached on the sample papers I have uploaded, so that I might use these example answers to answer future questions like them.
