The 2024 Alibaba Mathematical Competition Finals will be held from 0:00 to 24:00 on June 22, Beijing time, for a whole day. Contestants can choose to answer any 8 consecutive hours within this time window. This time arrangement should be enough for the contestants to complete the competition, because the contestants can allocate time according to their own rhythm and strategy to ensure that all questions are completed within the prescribed 8 hours.

However, it is worth noting that the questions in mathematics competitions are usually of a certain degree of difficulty and challenge, requiring contestants to have a solid mathematical foundation and good problem-solving ability. Therefore, although there is enough time, contestants still need to make adequate preparations before the competition, including reviewing relevant mathematical knowledge, improving problem-solving speed and accuracy, etc.

In general, the time arrangement for the Alibaba Mathematical Competition Finals is reasonable, but contestants still need to work hard to prepare to meet the challenges in the competition.
