Just went on to graduate magna cum laude from Dartmouth College in Hanover, New Hampshire. There, Just developed an interest in biology after learning about fertilization and egg development. Just won special honors in zoology, and distinguished himself in botany, history, and sociology as well. He was also honored as a Rufus Choate scholar for two years and was elected to Phi Beta Kappa. Just was also a candidate to deliver a commencement speech, but was not chosen because the faculty "decided it would be a faux pas to allow the only black in the graduating class to address the crowd of parents, alumni, and benefactors. It would have made too glaring the fact, that Just had won just about every prize imaginable." Including, honors in botany, sociology, and history.
