IOI-style problems sometimes require the checker to also compute the score (this problem is a good example). In some cases the checker is complicated enough to warrant having dedicated tests for it, but it is currently not possible to set the right expected verdict if the checker returns "partially correct" - there is no such option in the UI, and currently returning "PC" is reported as "CRASHED".
