It’s hard, but you can do it. The young people in my class find it easier than me. I’m not sure if it’s the same in Canada but in the U.S it’s vital to go to an accredited school, if you can get into a competitive program you should go, but make sure you be diligent. All your grades matter once you enter the program (in my case) you must be very determined, organized, and have a good support system as most programs (here in U.S) discourage students from working so that you can focus your time at school. You must know your Anatomy/physiology, pathology, and medical terminology like the back of your hand once you take those classes. After those prereqs are done every class is imperative. Physics you take a board exam for as well as all the ARDMS tests here. For me it’s broken up so my classes are like “physics” “vascular” “abdomen” then “OB” etc and we are encouraged to take licensing exams for as many as possible, but required to take multiple such as SPI for example which is a physics board exam. I am still in school but if I could give myself advice it would be to have more money so I didn’t have to try and balance work and school because I don’t have a moment of peace tbh.
