A market counts if the resolution depends solely on whether Tiger finishes a problem set.

Only a resolution in the direction indicating that a problem set was completed ends this market, e.g. "Will Tiger not complete a problem set" resolving YES does not count.

Resolves to the number of such markets created (must be referencing distinct problem sets, so multiple markets about the same problem set does not count) when this happens, including the 4 already created by @rewind .
