Haese and Harris Textbook

[indigoblue]

Hey everyone!
I'm new to Atarnotes, and I'm not sure if this has been asked before, but I was wondering whether the Haese and Harris further book is good enough to prep you for success in the exams? This the textbook our school uses, if not, do I need to use another textbook on the sidelines?
Also, what does it take to get about 45 ss? In terms of SAC and exam scores?

I can't say anything on the book as I haven't heard of it, but 45 SS means you're in the top 2% of the subject, approximately, so you'll really want to get as close to full marks as possible, especially in exam 1. Exam 2, you can maybe lose up to 10 marks, depending on the year, but you should aim higher.
