Tessellate S.T.E.M.S. 2019
Inspired by the success of the maiden edition last year, Chennai Mathematical Institute is back with the unique examination for high school and college students, S.T.E.M.S.
S.T.E.M.S. (Scholastic Test of Excellence in Mathematical Sciences), as a part of the college fest Tessellate, is a nationwide contest in Mathematics, Physics and Computer Science, which gives students an opportunity to show off their problemsolving skills, win exciting prizes and attend a 3day camp at CMI.
The camp features renowned mathematicians, physicists, and computer scientists from some of the best research institutes in India (such as CMI, ISI Kolkata, ISI Bangalore, IMSc, IISc, the IIT's). Students from all age groups have fair representation. It provides a great opportunity for the participants to interact with people at CMI and get an insight into academic life. The camp also features talks by students of the aforementioned institutes. Successful participants receive exciting prizes, along with certificates signed by some of the best academics in the country. The organizers will be providing the travel fare, food, and accommodations to selected candidates for the entire duration of the camp. Top 100 participants will be rewarded with a certificate of participation.
