No worries!
Pretty much all of Drawabox is essentially a test / exercise of your spatial reasoning skills / understanding of 3d space because it's all about conveying form on a flat page. But if you want a specific test of your skills you can pick any object and try to rotate it on a page kind of like the rotated boxes exercise from lesson 1.
The reason that 1 drawing per page is good is because you give yourself the whole page to understand the subject and how it sits in 3D space. The way you apply this to your drawings is by understanding that every form you put down on a page isn't 2D (unless you want it to be) and to treat it like a 3D object in the real world.
Feel free to ask questions if anything is still unclear!
