HSC Maths Practice Question Paper - Part1 - AA1

It has been some time since we were posting practice questions on HSC Mathematics. Finally, got some time to post some interesting and challenging questions to train your minds in Mathematics. In this new bunch of questions, we have a full question paper in Maths for you to work out and solve. It would be great if you can post the answers to the questions on this set to see how far you have fared. We have a total of 80 questions with 45 questions on one mark questions and the rest all are of five mark question types. The questions are generic enough and even if you are from a state board / matriculation standard 10, 11 and 12 you can make an attempt on them. We have named the question paper as AA1 and to navigate to subsequent parts of this question paper you can search with AA1 - Part(x). Happy solving.
