Do I have to take Physic in HS to be a Pediatrician?

In the USA (I assume, I don’t know where you are a student), it doesn’t matter one bit what classes you take in high school in order to be accepted into medical school. You will need certain pre-requisites in college (or in a post-baccalaureate program) to be admitted. These typically include two semesters of calculus, inorganic and organic chemistry, several biology courses and several physics courses. The MCAT test has components of these courses embedded in the exam, so, certainly being knowledgeable about these subjects will help get you into medical school.

The same can be said for how it works in Canada. If you do well in your classes next year that’s all the college or university you apply for will see. Imagine working for Admissions and seeing an an applicant’s transcript with Biology, Chemistry and Environmental Science, Psychology and Human Anatomy with grades in the +85% range and in seeing that the student wants to pursue Pediatrics says to herself, “Well, this is just, this just all wrong! No high-school Physics?! This student has absolutely no grounding the physical sciences!”

Seems a bit silly right? Of course it is. Just worry about keeping your grades up and in the end that’s all that will matter. Of course as shilolo said, once you get into post-secondary that’s when class choices begin to matter.

well even though they don’t look at it. Taking it won’t hurt, the more prepared you are for college by taking classes like that the better, because it doesn’t matter as much what undergrad school you go to, but it does matter how well you do during your undergrad years. so you could look at it that way. but no it doesnt directly effect your admission to a 4 year college

To get into a reputable medical school, you need a solid grounding in science and math, measured by your grades in lab science courses in college and by your performance on the MCAT, at least in the USA.

To get into a reputable college, you need a high school transcript that shows that you took difficult classes and did reasonably well in them. The actual classes don’t matter as much as the fact that they’re difficult and that you did reasonably well in them.

If you take physics next year, you’ll have an introduction to it, which will make your college physics class easier, so that’s a reason to take it. On the other hand, if you would rather take psychology, that won’t hurt your college chances, but all the stuff in your physics course will be new to you.
