報名須知

賽事第一階段：The Power Competition
賽事范圍：Power Round Test
賽事環節介紹：Power Round Test（能力測試）:?以證明題為主的測試，各支隊伍以團隊合作形式答題，作答時間不限，需在截止日期前提交。
注意：參加 The Main Competition的團隊和個人也需進行該輪測試。

賽事第二階段：The Main Competition
賽事范圍：Individual Round, Team Round and Live Round
賽事環節介紹：
Individual Round（個人測試）：每位參賽者需參加兩項測試，即從代數、組合、幾何和數論四個選項中任選兩項進行測試，每項測試時間60分鐘。該輪測試需個人獨立作答。
Team Round（團隊測試）：各支隊伍將得到作答要求和一套試題，需在約30分鐘內（具體時長將在學術活動當天公布）以團隊合作形式答題，該輪測試為非證明題。
Live Round（實時測試）：各支隊伍同時答題，答題過程中，各支隊伍可以通過實時評分系統了解其他隊伍的答題進度。

注意事項：

1. 開課時間：根據學生時間組班
2. 學員須知：
（1）受不同學校開學時間影響，班課具體開學時間可能會有微調，具體時間以班課學員為主
（2）班課時間一經確認不再變更，開課后每課若有超半數學員按時出席，則當天正常上課，如有特殊情況請提前告知協調
