Bench and Shoulder press - CrossFit Games Open 12.4 or Wall Ball, Double-unders, Muscle-ups

Started off with bench:
185 x 5
205 x 5
215 x 3
225 x 2
235 x 1
Not very good but I am not walking away from this lift.  Went on to shoulder press since it is a main crossfit lift and I suck at it.
135 x 3
135 x 3
135 x 3

Complete as many rounds and reps as possible in 12 minutes of:
150 Wall ball shots, 20 pound ball
90 Double-unders
30 Muscle-ups

I did all the Wall-ball and double-unders and 11 Muscle-ups.  I have never done this before but it was not too far from the post on main page so I will take is as a ok place to start.
