Get the Harry-Hermione mug.
Overachieving-ass dweebs (like Hermione) that are in all your biology and chemistry classes. They let everyone around them known that they are pre-med either directly or indirectly through their obnoxious behaviors (including, but not limited to: asking questions about how the material is relevant to the medical field, whether or not the professor has finished writing them a recommendation letter, and boasting about their shadowing experiences). An important thing to note is that not all pre-med hermione's are actually smart, but pretend to be.
Pre-med Hermione: "I'm getting my surgery next week. But I'm not worried; I've seen the procedure done like a hundred times."

Pre-med Hermione: "I can't wait to be a doc. I'm gonna be all like "Open your mouth, and say 'Ah'""

Pre-med Hermione: "Those pills are really bad for you. I would know. I'm pre-med."
