If you are looking for how to get a handicap and once you have a handicap index, this number is then used to determine a course handicap, which differs from course to course. As stated each course has a course rating and a slope rating. Golf handicap is determined by a formula that takes into account several factors such as scores achieved in past rounds and how difficult the courses those rounds were played on. You must have played and accurately scored at least 5 rounds, and no more than your last 20 golf round scores can be used to determine a golf handicap. To know more please visit the website.
