Leaving Certificate Agricultural Science Higher Level candidates had a challenging paper that required students to have a good overall knowledge of agriculture and current agricultural practices, said Donal Power of the Institute of Education.
Students that read around the subject and keep up to date with industry publications will have been rewarded, he said.
Mr Power said there was an attempt made on the paper to reflect modern farming and current agricultural practises, with, for example, questions asked on bull beef production and kale and maize and cross breeding in dairy.
He said students would need to have had a good overall knowledge of agriculture, as some of the questions were tricky and quite specific.
There was very little biology in the paper, which instead focused mainly on the agricultural aspects of the syllabus.
Lisa Carty Wallace of Yeats College Galway described it as a mixed paper that left students disappointed that there were not more questions on animal enterprises and grassland.
