Homeschool Data · 12th Grade
Across 34,216 twelfth-grade science courses on homeschool transcripts, Physics is the most common senior science (19%), the capstone of the lab sequence, but like Calculus it is reached by a minority.

| Physics | 19% | |
| Chemistry | 12% | |
| Anatomy & Physiology | 7% | |

Physics is the most common senior science (19%), the capstone of the Biology, Chemistry, Physics sequence. But the senior sample is the smallest of any grade (34,216, against 66,930 in 9th), because many students complete their science credits earlier. Anatomy & Physiology (about 7%) is a popular senior lab science, especially for health-career-bound students.
A fourth year of lab science is an opportunity to stand out, the science version of reaching Calculus. Only a minority of homeschoolers complete Physics or another fourth lab science; a student who does signals unusual rigor to admissions. That outcome traces straight back to starting Biology early and keeping the sequence moving.
Computer Science is a strong addition but not a substitute. It can count toward a college's science or math core (and toward the NCAA core if the school awards credit), yet it is not a lab science, so it strengthens a transcript alongside Physics rather than in place of it.
Physics is the most common, followed by Chemistry and Anatomy & Physiology. Many students have completed their science credits earlier.
Three years of lab science is the common expectation; a fourth, especially Physics or an AP, is an opportunity to stand out for selective and STEM programs.
