The Categories Selection box
In order to ensure your entry appears in the correct section, you need to apply a ‘category’ to the post.
When editing your post, you will notice a section along the right hand column labeled Categories. In this block are all of the possible categories you can choose for your post. If you are creating an entry for Challenge 1 and you are in High School, check the ‘Challenge 1 – High School’ category and your post will appear in that section once published.
