     The Mathematics Enrichment Saturday sessions are held in the Western Gateway Building, – building no 81 on this campus map. Here’s another map.

     The Final Round of the 28th Irish Mathematical Olympiad took place on Saturday, 30 April 2015. Here is the Roll of Honour.


     NEW: The  2015-2016 activities will start on Saturday, 7th November. Here is a description with schedules.


Follow-up for 5th-6th years

TY Maths Enrichment

Junior Maths Enrichment

 Maths Circles for 1st year students

Who:  Most of the participants have attended the UCC Maths Enrichment Classes in the previous year, but all students are welcome. The main condition for attending these sessions is willingness to do the homework! MC900433817[1]

Who:  Most participants are TY students who performed very well in the Junior Cert and/or in Round 1 of the Irish Mathematical Olympiad. 5th  year students and exceptional 3rd year students are welcome too. Participants receive invitations through their schools. Other places available upon request.

Who:  Most participants are students in their 2nd or 3rd Junior Cycle year who have attended a Maths Circle in their local school, or who have shown special interest and aptitude for Mathematics.

Who: Junior Cycle students in their first years of study, who are curious about mathematics and like maths games and puzzles. Some schools select participants based on their in-class results.

Using Math.EU resources.

When: Saturdays 10:00-13:00

7st November 2015 – 23rd April 2016


When: Saturdays 10:00-13:00

7st November 2015 – 23rd April 2016

When:  Sat 10:00-11:30

7st November 2015 – 2nd May 2016

No classes during school breaks.

When: Throughout the school year.

Why: Now the topics you met last year start to feel more familiar, the ideas sink in, and you find yourself a better problem solver. Smaller group, more one-to-one interaction.

You get a chance to participate in events like Mathematical Olympiads

Why: You encounter deeper, more challenging and more interesting mathematical problems than those on the school syllabus.

 You get a chance to participate in the

Mathematical Olympiads

Leaving Cert results

Why: To continue on with the fun of Maths Circles.

To meet like-minded people from other schools around the Cork area. 

To participate in contests like Alcumus challenges, or the Purple Comet   

Why: Testimonials

    Mathematical Olympiads


What are Mathematical Olympiads? Contests for secondary school students, they are designed to test and stimulate the creativity, intuition and mathematical skills of the participants. They provide a competitive but friendly environment for students with an interest in mathematics. There are local, national and international mathematical Olympiads. The International Mathematical Olympiad is the pinnacle of mathematical competitions among school students.

How can I prepare?

Here are some of the many fun competitions at local and national level which you can try prior to participating in a Mathematical Olympiad.




Mathletes challenge

January to May

Primary, junior and senior secondary school

Achievement Awards

All year

Primary, junior and senior secondary school

Irish Maths Teachers Association competitions

Contact IMTA at info@corkmaths.ie

Junior and senior secondary school

Kangourou sans Frontières competition


Primary, junior and senior secondary school

Prism competition


Junior and senior secondary school

Purple Comet international online team competition


Junior and senior secondary school


Most of these train your reasoning skills, speed and precision. In addition, Mathematical Olympiads typically require more advanced knowledge outside of school curriculum, along with perseverance and creativity. To practice this skill set, join one of our Mathematics Enrichment classes. Please check the schedules above.

Prior to the Irish Mathematical Olympiad in May, please review the lecture notes and exercise sets from our classes: click on the titles in the schedule page. As well, do check the resources offered by other centres in Ireland: the UCD Maths Enrichment as well as the Maynooth Olympiad manual. You can find more notes and practice with old Olympiad problems in the Maths Notes section of this website.


In addition, the following external links provide useful resources for national and international Olympiads:


Mathematical Database – the Elementary Mathematics section.  Olympiad Number Theory notes.  Olympiad Inequalities notes.  Yufei Zhaos Olympiad training notes.

Visit this Art of Problem Solving resource page for a large sample of international olympiads.

Where can I get more information? Visit the official homepage of the Irish Mathematical Olympiad.

The International Mathematical Olympiad is the most prestigious international mathematics competition for school age students. The first IMO was held in 1959 in Romania, with 7 countries participating. It has gradually expanded to over 100 countries from 5 continents.


Cork Maths Enrichment students at the International Mathematical Olympiad for the past 5 years:


IMO 2015

The European Girls' Mathematical Olympiad (EGMO) is an international mathematics competition similar in style to the International Mathematical Olympiad, aimed at motivating girls to develop their mathematical talents.Participating countries send teams consisting of four female mathematicians of school age.


The fourth EGMO took place in Minsk on April 14-20, 2015. The Irish team members were


 Antonia Huang from Mount Anville Secondary School, Dublin,

 Ioana Teodora Grigoras from Mount Mercy Secondary School, Cork

 Anna Mustata from Bishopstown Community School, Cork

 Katie O’Connor from The High School, Dublin

 The team leader was Dr. Mary Hanley and the deputy leader was Kieran Cooney. Congratulations to Anna for her Silver Medal at EGMO 2015!


The third EGMO took place Antalya on April 10-16, 2014. The Irish team was made of  Karen Briscoe from Kinsale Community School, Ioana Teodora Grigoras from Mount Mercy Secondary School and Anna Mustata from Bishopstown Community School.


The second EGMO took place Luxemburg in April 2013. Karen Briscoe from Kinsale Community School and Anna Mustata from Bishopstown Community School were awarded Honourable Mentions. Here is An Irish team member report by Jessica Weitbrecht and some photos.

Short history:   Mathematics Enrichment Classes at University College Cork

     The programme was started in 1987 by Prof. Finbarr Holland and Donal Hurley, with the support of members of the Mathematics Department at UCC. These classes meet for three hours on Saturday mornings and around 100 students attend them. Students are invited to attend the classes based on their performance at the Junior Certificate Mathematics Examination and teacher recommendations. Invitations to attend these classes are highly valued. The topics covered are generally distinct from the Leaving Certificate Mathematics syllabus and the emphasis is on solving mathematical problems which require ingenuity and mathematical techniques.Programmes involving Mathematics Enrichment Classes are to be found in many countries. They are generally very extensive, meet more regularly and involve a large proportion of students. Generous sponsorship is readily available for such programmes as many of the leading scientists and engineers in these countries would have some of their early training at these activities.
