Competition Broad Institute Crunch #1
1
  1. How many submissions are allowed for the first checkpoint on 30.11.2024 ? If we have a team, can each member also submit ?
  2. Do we need to submit before 30.11.2024 (aka on 29.11.2024), or is it also possible to submit on the 30.11.2024 ?

  1. You can have up to 3 models per person.
  2. You can submit until 2025-01-31 5 PM UTC. If you miss a checkpoint, it is ok, you will be scheduled for the next one.
