The exercise is relatively easy, the beginners however may have trouble figuring out how to approach and where to begin. This has a lot to do with lack of practise with options that can be used for creating reference planes and other reference elements. If you have not practised reference elements and are not familiar with the various options that exist, it's better to practise that first.

The part can be made with the use of pad, hole and stiffener commands. We may need to make a couple of sketches for this on different planes. Once you see someone make it, it becomes relatively easy since it give a perspective as to how such a problem can be approached. Going further, you would be able to come up with more unique ways to make such parts.
