WSDP Checkpoint

Here are the results for the WSDP checkpoint. In each column, the maximum possible score is first, followed by the baseline score, followed by all of the scores submitted in descending order. Note that a single row does not correspond to an entry submitted by one student; rather, each column is ordered separately.
