Hi Everyone, I hope that exam studying is going great for you. I compiled summaries from the textbook for each chapter so you dont need too. I work very hard on these and added multiple diagrams as well. I study at UNISA and I am not a huge fan of theory so this makes it easy for me to study just what is important and go into depth about it. Goodluck and all the best. I hope these help, they are totally worth it!
