I'm not sure how you got the idea that tracing is a good beginner exercise. All you're doing when tracing is drawing lines over the finished lines or outlines of a work. In other words, you're skipping almost all the steps of making a drawing. Even if you traced enough that you can repeat parts accurately from memory, you'd be stumped the moment you had a slightly different subject or a different angle, because you know none of the thought process that went into making it.
>>2491 says it helps with lineart and line control, but not even that is necessarily correct. You're not inking over your or someone else's pencils, you're just copying someone's inking, line for line. For drawing, you need an intuitive understanding of proportion, of perspective, of how 3D-Volumes work, as well as lighting, figure drawing and anatomy. With those, you can more easily understand the things you see, and that lets you figure out how an object or subject works, which lets you draw them more intuitively. If you're starting out, start with mechanical skills such as drawing straight or curved strokes, along with circles of various sizes, and combine that with trying to understand 3D objects. Draw an arbitrary shape on paper, then draw some contour lines until that shape starts to resemble a 3-dimensional volume. Then you can imagine a light source from one direction and try to imagine which parts would be in shadow and where reflected highlights would be. One exercise that you should always do, regardless of skill level is the study, especially from real life. How it works is that you try to copy what you see in front of you by breaking it down in a way you can understand, and reproducing it on a page. This is the most essential art exercise and it lets you practice all your fundamentals at once, while also giving you a deeper understanding of a subject.
