Test question: Partial credit for correct answer, second attempt

Can Lectora give 100% credit for a question answered correctly on the first attempt, but only 50% credit for a correct answer on a second attempt? I have a multiple choice test set up so the user cannot advance to the next question until they select the correct answer. The user is given immediate feedback (incorrect/correct) as soon as they select a radio button. When the correct answer is chosen, the next button appears allowing them to advance. The problem is Lectora is only remembering the last answer selected (the correct answer) so the test results are always 100%.

Is partial credit for a second attempt even possible in Lectora?

Can anyone point me in the right direction?
