That was my first assignment as a mentor. Think of it as a initiation. It will acclimate you to UnrealEd. It also demonstrates initiative, motivation, and will to learn UE4 on your part. These traits are also necessary to push through the tough times, where there is no example to work from, if you aim to develop something tangible. I learned on my own with help of those samples, tutorials and community, there is no easy way.
