How to improve your General Science score
General Science is broad and shallow — it rewards wide familiarity, not depth. Do not try to learn it all. Cover high-frequency basics in life science, Earth science, chemistry and physics, and stop. It does not count towards your AFQT.
The three mistakes that cost the most marks
Studying it like a school exam
The questions are recall-level and spread across every science. Reading a chapter deeply on one topic is a poor trade when the next question is about plate tectonics. Breadth beats depth here, which is the opposite of most study advice.
Over-investing when it does not count
General Science is not in the AFQT. It feeds technical composites like the Army's ST and GM. If your target job does not need those, time spent here is time taken from subtests that decide whether you can enlist at all.
Skipping the diagram questions
A reliable minority of questions are labelled diagrams — cells, circuits, the water cycle. These are free marks if you have seen the diagram before and guesses if you have not.
A drill routine that works
- 1Flashcards only, 20 minutes a day, covering biology, Earth and space, chemistry and physics in rotation.
- 2Prioritise: human body systems, cells, the periodic table basics, states of matter, simple forces, the solar system, weather.
- 3Learn the standard diagrams by sight rather than by reading about them.
- 4Stop once you are scoring consistently. There is no benefit to mastering this subtest.
How much can you realistically move it?
Quick early gains then a sharp plateau. A fortnight of flashcards gets most of what is available. Only push further if you are chasing a technical job that needs a strong ST or GM composite.
