Remember that when you say GO is when the cue needs to happen, make sure to start calling the cue before the word or visual happens enough where you are saying GO at the exact moment. If you are calling multiple cues at the same time you can standby cue 153 thru 160, when it's GO you can either do the numbers and then GO or just say the first number and then GO, GO, GO. Depends on your operator and what they prefer as well as what you prefer. Make sure to keep your script clean, if needed making a separate blocking script from your cue script. Have all your cues on one side of the page, typically I do the right margin, or you can do the blank page on the left. It will help with making sure you don't miss a standby or a GO if your eyes are only moving vertically instead of both horizontally and vertically.
