The MIT integration bee is a yearly maths contest at the Massachusetts Institute of Technology for students to battle it out by solving challenging integrals as fast as possible.
The qualifier test consists of 20 questions to be attempted in the space of 20 minutes. The top 16 students from this test then take part in the bee.
