What's good for medical students to take an interprofessional exam?

First of all, we can almost infer from your question that you don't know what you want to do in the future, but you just want to change your specialty to make it easier for you to find a job and develop in the future. This is one meaning of your word "good"; the other meaning should be that this specialty and the future work can use the medical knowledge and skills.

If this is the case, then the best choices would be an LLM (Unlawful Studies) and an LLM with no restriction on specialization.

This should be a wide range of future work, if you want to use the medical knowledge, you can enter the court as a forensic doctor or engaged in the management of medical appraisal, etc., can be engaged in medical malpractice disputes, lawyers, but also forensic work. If you don't use medical knowledge, there is a wide range of employment opportunities in law. But it is recommended to be able to combine the law and medicine, to engage in the legal profession is more advantageous.
