In the video prior to this challenge it'll go over the template syntax and how to drop into and out of the HTML output by surrounding ruby code with tags.

So for instance:

<% @statuses.each do |status| %>
  Name:   <br />
<% end %>

Those two opening and closing commands there, they're never displayed anywhere in the HTML at all, right? They're just there so you can "drop in" to ruby and execute a loop, which DOES output the following for each status in statuses:

Name: <br/>

So the question here is... how do you drop back into ruby for a moment after the "Name: " part and have the information actually display to the page?

You'll want to use the opening tag with an equal sign in front of it, to indicate the output should be put into your page, not just run in the background 

<%= "Stuff to be on HTML page" %>

So...

<% @students.each do |student| %>
  Grade: <%= student.gpa %> <br />
<% end %>

Hope that helps a bit.
