SLMC 8, 11 and 13 will be held on July 6th (tentatively) 
from 10:30 to 12 noon.

Please note that SLMC 2019 can not be held on April 27 th due to the closure of schools till April 29 th . Also, due to Edexcel and Cambridge Exams scheduled during May 2 nd to June 24 th we cannot hold SLMC 2019 during this time period. So SLMC 2019 is tentatively scheduled on July 6 th .

IMO and IMC teams will be selected from the top 50 Performers at SLMC 2018 who satisfy the age requirements of born on or after July 2nd 1999 and born on or after August 1st 2002 respectively. Selection tests are tentatively scheduled as follows:

IMO Pool Selection Test 2019 (IMO PST 2019): May 12th from 9 am to 1:30 pm at University of Colombo
IMC Team Selection Test 2019 (IMC TST 2019): May 11th from 9 am to 11 am at University of Colombo
Further Inquiries:
IMO PST 2019: Dr. Dayal Dharmasena (077 888 9929)
IMC TST 2019: Dr. Kaushika de Silva (077 350 6170) and Mr. Kapila Silva (077 912 4904)

Note: Selecting the IMO team has to be done on SLMC 2018 because there is no adequate time to do the selection from SLMC 2019. But in countries with strong IMO programs country’s IMO team is selected from an IMO pool selected previous year as it allows providing year-long training to the IMO pool and selecting the most motivated students for the IMO from the pool. So we will follow the same method this year by selecting an IMO pool for 2020 from SLMC 2019 later this year.

The Sri Lankan Mathematics Competition 8 (SLMC 8) is based on basic grade 6 mathematics and designed to let students have a positive experience in mathematics. All the students in grades 6-8, irrespective of their marks in mathematics at school tests, should participate in this competition. The Sri Lankan Mathematics Competition 11 (SLMC 11) and the Sri Lankan Mathematics Competition 13 (SLMC 13) are based on basic grade 8 and 11 mathematics respectively and designed to help students develop their mathematical thinking. Also, by participating in SLMC 11 and SLMC 13 students get the opportunity to participate in the international mathematics competitions TIMO, HKIMO, WIMO, IMC & IMO.
