Set assessment to end if certain % cannot be attained

Question

Greetings,
If I have an assessment simulation w/20 questions and a learner must attain 80%, is it possible to set up something that stops the assessment if the learner has no chance of passing?
Again there are 20 questions and say the learner misses the first 5, why continue if there's no chance of passing. Is there a way to set something up that says as much and re-directs them back to the training portion of the course?
Thanks!

Yes this is certainly possible, but it's not a piece of cake to pull off.
You'd need to set up user variables that track the questions the user has answered and then have Conditional Advanced Actions keep track of the user's current score so that, if at any time they crossed a threshold that eliminated the possibility of passing.  This Conditional Action would need to be triggered ON Slide Enter of each quiz slide. If the CAA detects the score cannot pass, it jumps the user directly to a feedback slide that informs them of the futility associated with their current attempt.  For simplicity sake, this slide would need to be immediately before the Quiz Results slide, because there are some other little wrinkles you'd need to allow for.
For example, unless your quiz scope extended to include all content slides, jumping the user outside the quiz scope would mean they could not make another attempt at the quiz until they relaunched the entire lesson again.  Assuming you DID extend the quiz scope (by placing a scored object very early in the project), then your user would still need to click the Retake Quiz button on the Quiz Results slide in order to reattempt the quiz they just failed.  This is why I suggested that your feedback slide about their quiz failure should ideally be just before the Quiz Results slide.
So the workflow would be:
User enters quiz scope when they click a button or click box on one of the initial project slides to begin the content.
They start answering quiz questions but fail too many in order to successfully pass on this attempt. 
Your custom variables and conditional advanced actions doing the math On Slide Enter of each quiz question, detect the failed attempt and jump the user to the Failure Feedback slide you've set up.
This slide tells them they can't pass the quiz on this attempt and instructs them to click Retake Quiz on the next slide (the Quiz Results slide).
Clicking Retake Quiz jumps them back to the beginning of the Quiz Scope, which in your case is the button or click box at the beginning of the content.
The user reviews the content again and gets another attempt when they get to the quiz slides.
Does this help?  If so, you need to work out the math that your variables and CAA need to perform in order to evaluate the user's attempt status as he/she enters each question.
