Hello! I am a high school student who grew up in America my whole life. i have a few questions regarding the topic of going to medical school in Pakistan:

  1. would i have to do undergrad before i go to med school ( like in america) or would i go straight to pakistan for medical school in Pakistan after high school?
  2. do u encourage pakistani american student to go to Pakistan for med ( the expenses, how long it would take to complete ,etc.)?
