Basically lets take a golf course that has a par of 70. If you play a few times and average about 94 then technically your handicap is 24. This is now your playing guide so if you score par on a hole you recieve points. Or if you go round next time in like 90 you have improved on your handicap however you have to keep it consistant before you can lower it.
A golf handicap is used to improve your game thus trying to lower it to scratch which is 0 par all around the golf course.
Trust me once you have a handicap and golf often it will improve your game.
