mate, the wealth of knowledge you need to know for engineering studies due to its crap and broad syllabus is not even worth it as it's scaling is abysmal (don't fall into the trap in saying "oh but it aligns well", well who gives a shit about aligning, at the end of the day if you want to go to uni, scaling is what matters). Never should you even think about going near this course (it was like Pandora's fucking box, i saw it was like "ewww it looks fun", but OH MY FUCKING GOD I WAS WRONG, BLOODY DEATH CAME OUT OF THE BOX, AND I HAD TO FREAKING LIVE WITH IT FOR A WHOLE YEAR), and please spread the word and save the countless generations of HSC students to come to avoid this shock horror of a subject. I even dropped bloody maths ext 2 for this shit, no doubt its up there with the greatest regrets in my life so far (what makes it worse math ext 2 is a godly scaling subject and i was ranked 2nd for math ext 1, stupid i know). HEED MY WARNING FUTURE HSC STUDENTS, NEVER AND I MEAN NEVER CHOOSE THIS SUBJECT OR EVEN THINK ABOUT DOING THIS SUBJECT, IF YOU CHOOSE TO IGNORE MY WARNING, IN ONE YEARS TIME DON'T COME BACK TO ME AND CRY YOUR BALLS OUT BECAUSE I ALREADY WARNED YOU. FOR THOSE WHO LISTENED, YOU CAN THANK ME IN ONE YEARS TIME WHEN YOU HEAR YOUR FRIENDS OR OTHER PEOPLE WHO HAVE FALLEN INTO LABYRINTH (AND YES THE ONE WITH THE FUCKING MINOTAUR) THAT IS ENGINEERING STUDIES. This is coming from a person who is ranked 1 in his school for engineering, so it's not from some dumbo whose to lazy to do anything in engineering (the worse thing to do in this subject), so don't take my opinion lightly. Well good luck for current engineering studies students for results and the suckers who are doing it for 2015 (if you have the option, drop it immediately or swap it with another subject pronto).
