San Diego Regional Practice: registration is now open

Existing Codebusters B/C test will be replaced by a different test by Thursday morning

Once school registration is completed, Regional team will assign team numbers then coaches can proceed with team rosters, event assignments, etc.

The sole objective of this practice is to introduce online testing to students who have yet had an opportunity to take online tests using Scilympiad platform. It is not content practice. The event tests are outdated and previously used for National SO Practice.

Event test schedule: 2/19/2023 10:00 PM to 2/24/2023 11:30 PM. Division B has 6 events and Division C has 5 events. 

Each event test has a time limit of 50 minutes. Due to open event testing schedule, there is no sequence of event tests teams have to follow. Teams can self-select sequence of their assigned event tests as to which test to take first, second, etc. Teams are not required to use the entire allotted time. Teams can move on to the next event test before the 50 minutes time limit.

There is no limit on a number of teams per school. You may want to take advantage of the unlimited number of teams and assign them accordingly. How about one student on a team so that they have a chance to practice online testing?
