Orthodontist Facts

Im graduated High School in two months. I've looked everywhere on the Internet for facts to become an orthodontist but I still need information. I know it takes a bachelor's degree, Faculty of Dentistry, and an orthodontic program. Any other information would be useful. Id like to know:
1) What major during the transition in my tank
2) What are the good universities to participate in both singles and dental
3) How difficult is it all
4) Any other relevant information
Thank you!

In general, a bachelor of science help. I strongly suggest watching the admission requirements for different universities to get an idea of what kind of courses they want, there are usually a list of courses Prerequisite. dental school is very competitive, especially if you want a good thing. You'll need a high GPA and you'll also need to pass the exam DAT, which is an aptitude test.
Ortho specialty is difficult, it is an extra four years of intense and monotonous work thereafter. The salary is very good.
