Sciences in high school

How many sciences must a student take in high school if he/she wants to do engineering in the US? Is it ok if only physics is taken? Which universities accept students for engineering with only physics

Most schools want to see a full science sequence of bio, chem, physics and then one AP (either chem or physics, although my dd will say that AP physics was the most useful class she took in HS for engineering).

Not to mention state requirements for HS graduation generally require more than just one science.

What year are you in school?

While true, the OP is an international applicant. So they will judge your coursework within the context of what is offered as well as what the school’s requirements are. Regardless, for engineering, the expectation would be science every year.

Totally missed that!

Engineering majors need to take physics at university, and usually need to take chemistry at university as well. (Biomedical engineering majors need to take biology as well.)

At US universities, physics and chemistry typically recommend high school physics and chemistry respectively as prerequisites (as well as calculus for physics). So high school students who want to attend US universities for engineering should take physics and chemistry in high school. Taking the university version without having seen it at the high school level may make it more difficult.

In general, it is preferable for those applying to US universities to have all of physics, chemistry, and biology in high school. More selective US universities often expect that plus a fourth science course at a more advanced level (e.g. AP, IB, A-level).
