So when they say you take 3 years of Science in Highschool in the US does that mean you take it all year long for 2 straight semesters or you take lets say Freshman year took Science for a semester Sophomore year another semester then Junior year another semester does that count as 3 years or what I'm confused? Cuz I heard 2 different answers

A year of science or any other subject means 2 semesters.
One-semester courses are listed as such.
What if I took Science in Freshman year for 2 semesters then Sophomore year I took Chemistry Biology and Physics for another 2 semester what would happen in that situation?
Are "Chemistry Biology and Physics" all rolled into the same course? Maybe an integrated science course? If so, then you would have taken 2 years (4 semesters) of science courses.
Yes all in the same year for 2 semester Physics Chemistry and Biology
