hi, my half yearly is coming up and i just bought the excel hsc gen maths textbook, just want to know what do you guys think about this book? is it good for revision and practice exams? btw during my study time i decided to study and read my school textbook first (new century maths) and then do questions in the excel book, do you think this study plan can get me a good mark? or do i need to do all the revisions in both books to achieve this? i really want to do well in this subject since it doesn't have a very good scaling
