Our website will be temporarily down for maintenance from 01:30 pm to 03:30 pm on Dec. 8 (Wed.) 2021.
During this time, the website will be inaccessible. We apologize for any inconveniences.
In some complicated evaluations, there are special bonus points, so we developed "Bonus task" feature. Bonus task's score will be calculated and displayed separately so as not to confuse the composition of the scores.
