Top Mathematicians score in the European Kangaroo Mathematical Challenge

Thursday, 3rd June 2010

Top Immanuel mathematicians Chana Bernstein, Aaron Rudolph, Joseph Berenson and Samuel Hilsenrath were invited to take part in the United Kingdom Mathematics Trust European Kangaroo Mathematical Challenge this year. These students were chosen based on their exceptional scores in the UK Mathematics Challenge. Over 5.5 million students from 46 countries in Europe and beyond took part in the 2010 Kangaroo paper. Being invited to take part in the Kangaroo Challenge is an impressive accomplishment itself, and to top it off Chana Bernstein scored in the top 25% of the 5.5 million participants from worldwide.
