Why are you claiming drawing "5" plans by "sketching that shit out somewhat to scale"?
Plans should always be drawn to scale. They're useless otherwise (unless you're in a very preliminary stage of design) and don't contribute to your aptitude as an architecture student.
to the OP. If you can't figure this out with your brain, a pen and a piece of paper, I would download Sketchup. Not only is it ten times easier to use than any CAD program, but there is an infinite amount of tutorials and how-tos online (youtube is good).
