There were no major surprises on a thought-provoking higher-level chemistry paper, according to teachers.

Tara Lyons, a chemistry teacher at the Institute of Education, said that while the paper didn't contain any surprises it did demand careful thought and a thorough knowledge of the course.

“Once again the old faithfuls – atomic theory, rates of reaction, equilibrium and water all featured as full questions. This should have allowed well-prepared students to maximise their grade.”

Ciara O'Shea, ASTI subject representative and a teacher at Scoil Mhuire agus Pádraig in Swinford, Co Mayo, said that the opening question, which was about vinegar, was a good start and would have settled students into the paper.

Warning symbols

The following question included some very accessible diagrams which will have rewarded students who completed practical work throughout the two-year course.

Ms O’Shea particularly welcomed the introduction of modern warning symbols on the paper which, she said, brings it up-to-date. “Overall there was nothing peculiar. Some of the questions had a slightly different phrasing from last year, which would have got students thinking, but there was nothing unfair.”

Ms Lyons said that that the paper moved away from rote learning but rewarded hard work and tested ability.

On the ordinary-level paper, Ms O’Shea said that it treated students nicely and that they were happy with it.

The question on organics was a nice opener, although some of the short questions will have been difficult for some students, she added.
