Psychology major to Biology major?

<p>I'm currently a Psychology major nearing my senior year, and I realized that the one degree that I've longed for is Biology, but first a bit of history. When I first started college I wanted to be a Doctor/General Surgeon. , therefore, I enrolled in a Biology major with a Pre-Med emphasis. After the rigorous coursework that I was not ready for, due to my military service, I downgraded to a more simple degree Psychology. It wasn't until recently that I've realized I still have the urge to work in the Biology field. My question is, should I switch majors abruptly or should I finish my Psychology major with the dreading Practicum and Seminars that will sap the greatest amount of energy? I'm passionate about the body, it's a knack for what I know ever since my introduction to biology my freshmen year in High School. I currently want to get into a Master's program in the field of Biology, such as Molecular or Developmental; however, I do not meet the requirements for any of them. Consider this my plea for help. My wife is already aggravated with me for being wishy-washy with my graduate plans, but it's because its difficult to find an area that holds my interest.</p>
