Uh oh! That moment you realise you've added too many hours, and now you need to delete some to make it right.
No problem! To delete any hours added by mistake:
Log in to your account
Go to your profile (click on your name in the top right hand corner of the screen)
Scroll down to the relevant opportunity
Click on the tab 'Hours and evidence'
Click delete on the hours you no longer want
Confirm and close the pop up screen
Go back and click the '+' sign to add the correct hours (don't forget to add a note to explain what you did to gain said hours and what skills you gained!).
