The old standbys work best. Philodendron is available in several varieties and it will climb or trail around your room. Sanseveria is something you see in malls and offices, where they thrive on neglect. For something unusual, consider Zamioculcas zamifolia (or "zamio" for short) and/or a fern or two that will grow in shade.
Really, even orchids are so inexpensive these days you could try one or an African violet or some ivy. If they die or fail to thrive you won't have lost much and you will have learned something.
Good luck and study hard!
