Navigate to the PPC Dashboard and click on the name of your first round campaign, Practice Campaign.
From here you can navigate between the Ads, Ad Groups, and Keywords tabs.
You can edit anything in those tabs that have a little blue pencil next to it.
Or you can add new keywords or ad groups to your practice campaign instead of editing what you already have. You can do this by clicking on the + Add Keywords button and then selecting the Ad Group you want to add keywords to, and then search for your keywords.
