I made an activity (all multiple choice) and I want to add a slide at the end that tells the student how many slides they got correct. How do I do this?

A few things to do, but not too difficult.

1. You’ll need to give your MC components unique names (e.g. mc1, mc2, mc3, etc.).
2. In each MC’s CL, make a variable for that screen’s score. Change the number to match the correct choice:

```auto
score = when this.isSelected(4) 1 otherwise 0

```

1. In your final slide, probably in a note, you’ll total up their score.

```auto
total = "${numericValue(`${mc1.script.score}+${mc2.script.score}+${mc3.script.score}+${up to your last}`)}"

```

1. Last make your student note “You got \_\_\_ correct.” where you’ll select the {#} button, instead of the blank, to select the total.
