SOME students left happy, some a little flustered, but one thing they all agreed on was that yesterday’s HSC maths exam was more difficult than expected.
As Orange High School students filed out of the exam yesterday, the overwhelming opinion was the test was one of epic proportions.
Year 12 student Laura Manca said of all the exams so far, maths was the most challenging.
“I was hoping for a band six from the maths exam, but after that I’ll be satisfied with a band five,” she said, a little disappointed.
“Some of the questions were very difficult.”
School captain Lachlan Jensen agreed, but was glad the test was a challenge.
“I’m not thrilled with how I went, but overall I was happy. I’m happy that I’ve got it over and done with,” he said.
Orange High School principal David Lloyd paid tribute to the students, who he believes will pass with flying colours.
“I’ve been really impressed with the maturity the guys have shown in their approach to these exams,” he said.
“There’s been a really strong vibe among the students and I’m fairly confident most of them will do really well.”
