Hi Drego,
Similarly to the 250 box challenge, you'll be using line extensions to check your ellipse alignments (in the first section) as well as your perspective estimations (in the second section) and gradually improve them by iteration and using the extensions to self-critique.
It is necessary to go though many reps to develop an intuitive sense for how to draw a cylinder (or a square plane, for the boxed cylinders) in any orientation, proportion, or rate of foreshortening you choose. This will come in very handy for the hard surface constructions in lesson 6 and 7.
