Our goal here at BigBinary Academy is to make learning easier. Without your feedback we will not be able to improve it. Send an email to firstname.lastname@example.org with your feedback.
If you are happy then let us know. That will motivate us to continue working on it with gusto.
If something is confusing then also let us know. We will change the content to avoid the confusion.
If you found a bug then also let us know. We will fix the bug.
If you think some material is missing or it is incomplete then also let us know.
In short let us know how you feel. We are looking forward to the feedback.
