Here is a idea of what a recent Q I entered was like.
First Series - Land Triple with bridge bird on water, no retired
Video -
Second Series - Land Blind. Line for blind was moved inside first series set-up. They put a gunner station about 30 yards away from line that fired a dry pop while walking to the line, and about 10 yards to the right of direct line to blind. Once dog got out about 100 yards, the long gun from the first series came into view, although it was approx 20 yards to the left of the actual blind, for suction.

Third Series - Water Blind, through keyhole, through stickpond.
Picture -
Fourth Series - Double, with retired gun. Long bird had three entry / exit from, water before having to push up hill to retired gun.
PIcture -
Some of the other Qs I have seen are as follows (note I have not run but a few)
First Series - Wide open triple, usually with long retired gun.
Second Series - Land Blind, usually with some interaction of guns in first series (whether it be a gun stays out to run past, flyer crate says out for suction, etc.
Third Series - Water blind with point cross, etc.
Fourth Series - Either water triple or double with retired. Bridge birds from one point to another. multiple entries.
I second, or third, attending one if you can prior to entering. It will give you a good idea of what you will be looking at.
I also second, or third, training above the level you are competing. You most likely heard when training for hunt test. be ready for senior before entering junior, be ready for master before entering senior. be completely finished before running master. The same concept applies here. If you train to the minimum, you will not have as much fun or success, than if you train to a high level.
Good luck. Take the plunge, and enjoy it.
