Unless it's one of these agencies--IMG, Marilyn, the Lions, the Society, Next, Women, DNA--you have more to lose than gain. Why, you ask? You will owe your agency A TON of money in the beginning and dig yourself into a hole of even greater debt. You will have to pay for polaroids and headshots taken for your book before your agent sends you out on castings. Then, you will actually need to book jobs to pay them back. Unless you look like Taylor Hill or have connections like Gigi Hadid and Kendall Jenner, you probably will book very few jobs in the beginning because people won't know who you are. Realistically, it will take 2-3 years before you are start steadily booking jobs. And if and when you book jobs, you will need to travel for shows and shoots, which means you will have to miss class. This is maybe possible pre-clinical years if your lectures are recorded and 100% not feasible during third and fourth year. Forget the late night binge eating before exams, because your agent will be constantly telling you to lose weight, tone up, and to lose an inch off your hips or you'll be dropped. Last and not least, you will absolutely need a clause in your contract for no nudes/ smoking shots. The modeling world is not exactly synonymous with professionalism and integrity. If I were you, I would focus on medical school and forget modeling.
