Hi, I'm 22 y/o medical student and 7 month later, I have very hard exam(like USLME step 2 in America). and as I now my self and due to my recent experience, I become anxious and lose my concentration near the exam. Also one of our professors suggest me to use SSRIs. Hopefully,I have no other sever medical issue like panic attack or General anxiety disorder or etc . Would you mind helping me to select between Sertraline or Fluoxetine? and your recommendation of its dose? Thanks a lot.
