I am currently working as a housekeeper at a hospital in Canada and wanted to become a sonographer. To be honest I am 28 and never had an opportunity to settle down in life and be financially at peace. After years of research and being exposed to the hospital environment, I have noticed this field and I was much impressed by the pay as well. I am a quiet person who just want to become the best at what I do. Unfortunately I did not studied biology at high school. But I majored in physics maths and computing. I was wondering if biology is a must. I believe I can pass the medical terminology exam with flying colours but just worried about not having biology at high school. Has anyone made it despite not having biology as main subject at high school
