There will be 3 separate scores for this WOD.  One for each interval.  Challenge yourself to really push through these intervals.  The worst that could happen is you have some extra time to rest between rounds!  The weight should go from moderate to light as you progress through the weight changes, so pick weights that well accomplish that for you.
