The UKMT has been involved in Kangaroo activities for over 10 years (see Intermediate Kangaroo) and more recently has started using hour-long Kangaroo-style papers as one of the follow-on rounds to the Senior Challenge.
The Senior Kangaroo 2015 merit (top 25%) threshold was 50+
Please note this is for guidance only; thresholds are recalculated each year based on the national score distribution.
The Senior Kangaroo is sat by invitation only.
There is no fee for entry (and it isn't possible to enter by paying a fee). Following the Senior Challenge, 3,000 or so candidates in the UK, who have not qualified for BMO1, are invited to take part in the Kangaroo.
The Senior Kangaroo is a one-hour paper which is sat in school. All the questions require 3-digit answers (using leading zeros where necessary) entered onto a machine-readable sheet similar to those used for the Senior Challenge. This is the first competition of its kind to be organised by the UKMT i.e. a challenge which is not multiple choice but which is nevertheless marked by machine.
Certificates of merit are awarded to the top 25% and certificates of qualification to everyone else who takes part.
