I am a level 6 too, and i also have fears of the BWO on high beam, so i can't really help you with that

. For your front handsprings, make sure you have a lot of heel drive (kick your heels over really hard). For your clear hip, (back hip circle w/o hips) your toes are supposed to shoot out at 3/4 of a handstand before you go into your second kip. A drill that we do at our gym (other than just having a spot on it) is to set up 2 wedge mats behind the bar (the side your feet are on in a cast). place them apart a little bit so you have enough room to cast in between the 2 mats. Do your clear hip with the mats there, and try to shoot up, and when you are coming down, shoot your feet up and place one foot on each mat, w/o your hips touching the bar. Another really good clear hip drill is the one that our gym calls the Tower of Terror!! It is fun!! We put 2 planks of wood from the high bar to the floor and set a mat on it. (a 8" mat). You cast and put your feet on the mat to start out. then you push away from the mat and do your clear hip trying to shoot your toes towards it. We play a game with this drill, if you would like to no what the game is, please private message me

. Here is a video of this last drill that i found:
YouTube - gymnastics - FANTASTIC set-up for Bars
I don't know who these people are, but that is the same drill our gym uses. If you have any ?'s please feel free to ask me

.
Good luck!!
