Prepare for the 80-minute Science subtest with life science review, physical and earth science practice, graph interpretation, experimental reasoning, PSI test-day checks, and score planning.
HiSET Science is not just vocabulary. Students need to read scientific information, interpret data, identify evidence, understand experiments, and apply core science ideas under time pressure.
Science prep should balance content knowledge with interpretation of experiments, tables, charts, and evidence.
The current HiSET Test at a Glance lists Science as 60 multiple-choice questions with an 80-minute time limit.
HiSET technical-manual categories list Life Science at about 49%, Physical Science at 28%, and Earth Science at 23%.
The test measures science content knowledge, scientific inquiry, and interpretation and evaluation of scientific information.
A subtest score of 8 out of 20 passes; 15 out of 20 indicates college and career readiness for that subtest.
Many HiSET Science questions ask students to interpret a passage, chart, table, or experiment before choosing an answer. Candidates should practice separating observations, claims, evidence, and conclusions.
Life Science is the largest listed category in the current technical-manual distribution. Students should review cells, body systems, heredity, ecosystems, organisms, environments, and biological relationships while keeping time for physical and earth science.
Scientific inquiry questions often require identifying variables, reading trends, comparing data, evaluating whether evidence supports a claim, or selecting the best next step in an investigation.

HiSET Science is the science subtest in the PSI-powered HiSET high school equivalency battery. The current HiSET Test at a Glance lists Science as an 80-minute multiple-choice subtest with 60 questions that measures the ability to use science content knowledge, apply principles of scientific inquiry, and interpret and evaluate scientific information. Official content categories list Life Science at about 49%, Physical Science at about 28%, and Earth Science at about 23%. A strong prep plan should combine biology, chemistry, physics, earth science, graph reading, tables, experimental design, variables, evidence, conclusions, and real-world scientific reasoning rather than memorizing isolated terms only. Candidates should also confirm state eligibility, myHiSET account and ID matching, accommodations, test center or online-proctored availability, and score requirements. HiSET score guidance lists 8 out of 20 as the passing score for each subtest, 15 out of 20 as the college and career readiness level, and 45 out of 100 as the total passing score across the five subtests.
The current HiSET Test at a Glance lists Science as 60 multiple-choice questions with an 80-minute time limit.
HiSET content categories include Life Science, Physical Science, and Earth Science.
The current HiSET technical-manual distribution lists Life Science as the largest category at about 49%.
HiSET says Science measures science content knowledge, principles of scientific inquiry, and the ability to interpret and evaluate scientific information.
HiSET score guidance lists 8 out of 20 as the passing score for each subtest. A 15 out of 20 indicates college and career readiness for that subtest.
Check state requirements, test center or online-proctored availability, ID rules, accommodations, and myHiSET account details.
Use practice questions to identify misses in life science, physical science, earth science, data reading, and experiment interpretation.
Drill variables, controls, hypotheses, graph trends, evidence strength, conclusions, and real-world scientific reasoning.
Complete timed mixed practice and compare performance to the 8-out-of-20 passing level and 15-out-of-20 college and career readiness level.
