Oh the pain! It burns!!
So frustrating, but it happens to all of us. The nice thing is, Lobster Ink assessments are not ‘one try only’ - you can repeat a Lobster Ink assessment as many times as you like until you pass it. While your foul luck may have made you miss out on your shot at a Gold medal, you can still re-write the assessment until you get 100% to earn that sought-after ‘Master’ medal.
A hint for next time - once you’ve started an assessment, if you have to leave an assessment, something happens like a power failure or computer issue, you can still log back in within the time limit of that assessment and continue where you left off. It’s only when the time runs out that the assessment will be automatically assessment.
