What happens when u become a doctor what are some neccesaties

you need 3 years premed at college then 4 years of med school, after that you can choose to do 5 to 7 extra years depending on the speciality you chose

Explanation:

after you finish the first 7 years (premed + med school) you can start working at a hospital as a resident for 5 to 7 years like I said depends on what you chose (to do that you will have to choose what speciality you want example plastic surgery or ortho) and while working as a resident you can start earning money.

To become a dentist is a whole different thing, if you wanna then ask me.

Of course, you have to work really hard along the way and you will have to do a lot of exams.

it is really fun tho, if you work hard you can have a lot of fun at the same time and make a lot of friends

You could look it up or just study it in college
