Changes are coming to the GRE subject tests. They are:
- After the April 2023 administration, the Chemistry test will be discontinued.
- The Physics and Psychology tests will be shortened to two hours.
- After April 2023, the Mathematics, Physics and Psychology tests will be offered on computer at test centers, and via at-home testing.
Read about these changes on the ETS website.
The subject tests have really been whittled down to just the basics. The Biochem test was eliminated in 2017, while the Biology and Literature tests were eliminated in 2021.
