Which CSET Science subtest is biology, chemistry or physics?
Biology is Life Sciences (217), which leads to Science: Biological Sciences. Earth and Space Sciences (219) leads to Science: Geosciences. Chemistry (218) and Physics (220) are their own concentrations. In every case you also need Subtest I.
What you get on screen
- A scientific calculator, for every CSET Science subtest
- A periodic table, for Subtest I and the Chemistry Subtest II
- A reference sheet of constants and formulas, for the Physics Subtest II
Some written answers are worked by hand on a response sheet and scanned in.
