Math Day 2015 Results



1,523 students from 98 Nebraska high schools participated in the 26th annual UNL Math Day on Thursday, Nov. 19, 2015, on the UNL campus. This event is designed to spark high school students' interest in math, to encourage them to pursue a career in mathematics or the mathematical sciences, and to recognize outstanding mathematical ability.

This all-day event consists of the PROBE I and PROBE II individual competitions and the fast-paced Math Bowl double elimination team competition. Students start with the multiple choice, preliminary exam called PROBE I (Problems Requiring Original and Brilliant Effort). The top three females and males receive awards. The top five, four, or three scores (depending on class) from each school determine the PROBE I Team score. The top 40 students move on to take an essay exam called PROBE II. The top 10 on PROBE II are awarded a total of $34,000 in four-year scholarships to UNL.
