Before you can calculate your golf handicap you need to submit 3 scorecards with all 18 holes played.
Once you have done this, click on the Handicap Calculator button on the dashboard:
You will then be prompted to select your last 3 scorecards. This will be done for you but if you would like to change them you can.
You can then click 'Calculate Handicap'
If you choose, you can update your handicap tracker with the calculated handicap.
