Video challenges are a new type of challenge in the freeCodeCamp curriculum. They are currently only in beta and not available yet on freeCodeCamp.org.
A video challenge is a small section of a full-length video course on a particular topic. A video challenge page embeds a YouTube video. Each challenge page has a single multiple-choice question related to the video. A user must answer the question correctly before moving on the the next video challenge in the course.
The video challenge pages are created by members of the freeCodeCamp team. YouTube videos are also uploaded by members of the freeCodeCamp team. Many of the video challenges do not yet have questions associated with them.
You can help by creating multiple choice questions related to video sections and adding the questions to the markdown files for the video challenges.
## Challenge Template
Below is a template of what the challenge markdown files look like.
- [How Neural Networks Work Course](https://github.com/freeCodeCamp/freeCodeCamp/tree/next-python-projects/curriculum/challenges/english/11-machine-learning-with-python/how-neural-networks-work)
Pick a challenge markdown file from the options above.
### Skim through the video associated with the challenge and create a mutiple choice question
First, find the videoId.
For example, in the following code from the header of a video challenge markdown file, the videoId is "nVAaxZ34khk". On GitHub, the information could be layed out in a table format.
```
---
id: 5e9a093a74c4063ca6f7c14d
title: Data Analysis Example A
challengeType: 11
videoId: nVAaxZ34khk
---
```
Next, access the YouTube video with that videoId. The url for the video will be:
https://www.youtube.com/watch?v=[videoId] (add in the videoId to the URL)
In the example above, the url is https://www.youtube.com/watch?v=nVAaxZ34khk .
You can add the question locally or directly throught the GitHub interface. To add the question locally, you need to [set up freeCodeCamp locally](how-to-setup-freecodecamp-locally.md). You can also find the file on GitHub and click the edit button to add the question right in your browser.
If a question has not yet been added to a particular video challenge, it will have the following default question:
```yml
tests:
text: Question
answers:
- one
- two
- three
solution: 3
```
Update the word “Question” with your question. Update the “one”, “two”, and “three” with the possible answers. Make sure to update the solution number with which answer is correct. You can add more possible answers using the same format. The question and answers can be surrounded with quotation marks.
Questions and answers can contain certain HTML tags like `<br>` for a new line. Surround code with `<pre></pre>` You will need to add a `<br>` at the end of each line of code.
text: 'What will print out after running this code:<pre>width = 15<br>height = 12.0<br>print(height/3)</pre>'
answers:
- '39'
- '4'
- '4.0'
- '5.0'
- '5'
solution: 3
```
```yml
question:
text: 'Below is code to find the smallest value from a list of values. One line has an error that will cause the code to not work as expected. Which line is it?
<pre>
1|smallest = None<br>
2|print("Before:", smallest)<br>
3|for itervar in [3, 41, 12, 9, 74, 15]:<br>
4| if smallest is None or itervar ⋖ smallest:<br>
5| smallest = itervar<br>
6| break<br>
7| print("Loop:", itervar, smallest)<br>
8|print("Smallest:", smallest)<br>
</pre>'
answers:
- '3'
- '4'
- '6'
- '7'
solution: 3
```
For more examples, you can look at the markdown files for the following video course. All the challenges already have questions: [Python for Everybody Course](https://github.com/freeCodeCamp/freeCodeCamp/tree/next-python-projects/curriculum/challenges/english/07-scientific-computing-with-python/python-for-everybody)
After creating one or more questions, you can commit the changes to a new branch and [open a pull request](how-to-open-a-pull-request.md). Make sure that you target the branch 'next-python-projects' and NOT 'master'.
