We have received a lot of questions over the year from high school students who want to study medicine in the US. We know that in Egypt you can get good grades and jump right into medical school. In the US, however, that is not the case.
In the US, you go to university for four years but you cannot study medicine. What you do instead is take "Pre-med" classes, which means you can use your undergraduate studies to finish the requirements needed to apply for medical school.
Medical school thus happens after you complete your 4 years of undergraduate studies.
