It’s completely up to you how to give points to every question. For example you can give 5 or 10 points to every question of an entire quiz. This is the simplest way to go in scoring points.
However, you may also want to create a quiz consisting of questions with varying difficulty. For example, you may want to award a higher point (say 10 points) for answering a tougher question compared to an easy one (5 points). The different weights in scoring gives some variety to your quiz.
Double-click a question on the left panel to pull up the “Properties Window”.
Scroll down to the middle of the window and locate the “Points for Correct Answer” box. Type the points you want to award for a correct answer to the question.
