Does it make sense to apply for research positions requiring a bachelor's degree with graduation still 4 months away?
My lab conducts a search for post-baccalaureate fellows every year. In most cases, the applicants are completing their final year of their undergraduate study and have an anticipated graduation date, and are able to share reference letters and a transcript with us. At least in my field (neuroscience) it's completely normal to apply for a post-baccalaureate position before you have officially obtained your degree.
