I got A for SBJ, so my trick is:
Let your feet be the foremost part of your body during the jump,
tuck them in.
If you do this properly, you will not even risk falling on your
ass. Land like a ball, rolling forward and using your hands to
break the fall. Keep your feet planted so the distance can be
recorded.
This was the only station I passed 
Now I’m downgraded, don’t give a shit anymore.
