→Rules to follow: Note on not using tab
And each of us should set up Visual Studio to turn off TAB otherwise we can lose marks.
Note from Matthew: Look into the program you are writing on to see if you can set the number of characters your tab key will indent. For myself, I write all of my code on an application called SubEtheEdit on my mac and I can set my tab to the 2 characters we specified, so I can easily still use tab personally.
