If you have completed the task of creating a task queue, can you please send along a screenshot of the task queue as well as the name of the task queue?
That is the only step showing as not complete at the moment.
Just go into either the Contacts, Companies, and Deals on the main navigation bar or from your Tasks dashboard. Create a task and related task queue. Successful completion of the steps involved will resolve this issue.
For your sales certification, I can see you have passed and everything is complete.
For your contextual marketing, you need to complete one more task: the email subject personalization task. Once you have completed that, you should be all set!
