Question on Rules of Golf:

Hi Ann. Thanks for writing MyGolfInstructor.com. I'm excited to get to help you with your game.

According to the USGA you must cut your 18 hole handicap index in half. You always round this number up to the nearest 10th. Then you use the 9 hole slope rating from the tees you play to calculate your handicap.

For instance if your handicap is 40, then you cut that in half to get 20. You then take the course slope from your tees, say that is 120 and follow the following formula:

20 x 120/113 = 21.2 (113 is the average slope)

So your 9 hole handicap would be 21.2.

I hope that helps and let me know if you have any other questions.
Thanks.
