Today I got home after a long day at my 9-3 and decided to watch a quirky little bit of HSC Advanced Maths from my favourite creator, McGrathematics. "Oh, trigonometric identities! My favourite!" I squealed with delight as my fingers danced above the keyboard and then shot to my mouse. Drooling, I watched as the legend himself, my idol and deity, explained the intricacies of a few new trigonometric ratios and how they might appear in the HSC exams to come. Suddenly, my pupils constricted as I reeled back from my computer screen. An error in example 3. Question C appeared different to the booklet I had so graciously been given. I slowly calmed myself down, "Mistakes happen right? Even to the best of us, " I lied to myself, for I did not know what was to come, as when I moved to example 4, another error was present. I cried non-stop for an hour, "How could our guardian angel fail us?! Is this a sign? Is anything true anymore?" I wailed, writhing on the floor in a pool of tears.


I will never be the same again.
