Try to do blind judges, wait for the moment when the lines go slack a bit to initiate the pull and rotation to pass the bar.
Make sure you throw your legs to the front. Also important is your hip- shoulder and especially your hea movement, anticipating the rotation.
Always keep bar as close to your hip as possible.
It makes it easier to tweak the railey out to get a better momentum for the rotation.
I would go too high and pop too hard for the first blind judges
you will get it just keep trying
