I am now a freshman and a medical student. I am also very interested in English. I would like to earn some money by doing some medical translation and interpreting work before becoming a doctor.

Being a medical translator requires not only good translation and interpretation skills (this requires at least 2 years of professional training), but also very professional medical knowledge. You are just a freshman, so you are not familiar with medicine. It can be said that the knowledge is basically zero. Generally, those who work as medical translators must have studied medicine to at least postgraduate level and have good medical English. So if you are willing to be a medical translator, you can study hard and accumulate at the undergraduate level to train your translation skills, especially to strengthen your medical English learning.
