An exam question about crickets has gone viral on social media and even become a meme after students complained about how difficult it was to solve

Students in Australia have been left baffled by a Higher School Certificate exam.

On Monday (October 26) a number of Year 12 pupils sat a standard mathematics exam but found one question on the test to be particularly challenging.

According to news.com.au the syllabus was recently altered by the NSW Education Standards Authority (NESA), which sets the exam papers.

One of these changes, saw some of the same questions feature in both the standard and advanced maths tests.

And a duplicated question about chirping crickets caused major issues for pupils – even sparking a meme on social media after the exam had finished.
