Pay attention to the letter oi oi said a number was. If you know you have the correct answer, but the letter isn't what was posted, for example, you got letter d for number 5, but someone else got letter b for number 5. If you know d is the correct answer, don't follow the answers on it; they will be wrong for the questions chosen for you.
