A major cause of youth suicide. Occurs over the final year of school for Australian year 12 students and largely involves remembering a fuckload of useless information that will either make or break your life, depending on your ability to remember it. Its a real prick and often incites hatred of not only onself, but teachers, the school and just society in general. A major contributor towards manic depression, drug dependency and insomnia. Students often remark that it leaves them scared for life, unable to stop analysing every film they watch or forgot the lines to Felix Skrzynecki poems (a rather useless poet whose only achievement is to manage to write a series of poems, each with the same theme, which feature various complaints about his parents, country and just his life in general). Likewise, the HSC is directly linked to both an increase in youth binge drinking but also a major contributor to greenhouse gas emissions and thus global warming.

Australian (specifically from the state of New South Wales) Higher School Certificate. A prerequisite for undergraduate students aspiring towards entering into university and uses a ranking system to facilitate in the generation of a UAI (Universities Admissions Index). Rather than allowing individual universities to set specific exams for potential candidates, the HSC centralises the process.

One of the most gruelling of any type of exam, by any standard. Taken in Australia, in the final year of schooling, the HSC determines your UAI, or University Admission Index, and subsequntly, your life.
The English exam(s) alone require the candidate to memorise 16 texts to quote from.

These exams have caused countless teenage suicides, and mass depression in adolescents, which causes excessive drinking and debauchery, and consequently, suspension, lowering the opportunity to learn and succed with this increddibly painful ordeal.
