If you must practice by your lonesome...my 2cents...

Don't ever assume you are flying wings level. Don't ever assume you are flying parallel to the flightline.

Get as proficient as possible at each individual manuever with proper pace throughout (from entry to exit). Then practice them in groups of three (in their respective order). Only if you are confident with each manuever's geometry and pace (make the speed/pace as constant as possible among manuevers) can you then put them together in a sequence. The sequence should be presented as seperate manuevers connected with excellent quality level flight paths between. Practice the tee shot, practice the approach shots, practice the short game. Play it from the tee to leave a good look at the green, approach conservatively to the center of the green, then putt to lag it at the back of the cup. Now do this 18 times in a row and you have a good flight sequence.

Good luck.
