For help entering a score, start here.
Once you've gotten to the score submission page, you'll notice a certification check-box next to "I completed the workout according to the written standards for this division."
If you completed the workout as it is written for your division, you should check the box. If you are in a scaled division but completed the workout as it is written for the scaled division, you should check the box!
If you made a modification in any way from the workout as it is written for your division, you should not check the box.
