I bought this book (at Protea)but the link in the book takes me to the website with only multiple choice quizzes. Is that what supposed to be there? I thought there is supposed much more e.g. solutions to end of chapter exercises , etc. The book is written 'ALTERNATE EDITION' at the top right corner of the front cover . Every other description matches what is the tutorial 101. There is no web access code/key is the book and is printed in Singapore. Is this the correct version? Lecturer may you also respond!!!
