Drawing cyclohexane so that it looks like a chair can be the key to appreciating the axial and equatorial positions. If you are unable to draw good-looking structures that clearly show axial and equatorial positions, then your instructor is probably going to assume that you don't know what you're drawing.
By not mastering the trick of drawing cyclohexanes the only person that really suffers is you the student. The first step is drawing the chair itself. Although the chair "looks better" when slightly angled, it maybe easier to "learn" to draw it with the middle portion horizontal.
