The TEAS 7 science section is where applicants lose the most marks

The science section is 50 questions in 63 minutes, and it is the section where the gap between a 60 and an 80 is usually decided. It is also the section people prepare for least efficiently, because "science" sounds like it could mean anything.

It does not. The blueprint is public and it is lopsided.

Anatomy and physiology dominates

Roughly 44% of the section is human anatomy and physiology. If you learn the eleven organ systems properly — structure, function, and how each one fails — you have covered nearly half the section before touching anything else.

Learn them in the order the body uses them, not alphabetically. Cardiovascular and respiratory together, because gas exchange links them. Renal after cardiovascular, because filtration depends on pressure.

Scientific reasoning is free marks

Around 9% of the section tests experimental design: independent and dependent variables, controls, and what a result does or does not let you conclude. This content is small, learnable in an afternoon, and comes up every time.

The recurring trap is a question that asks what an experiment proves. Correlational designs do not prove causation, and the option claiming they do is always there.

Chemistry is narrower than you fear

You need atomic structure, bonding, states of matter, the pH scale and basic reaction types. You do not need to balance complex equations under time pressure. The pH question in particular is nearly guaranteed, and it is nearly always about the logarithmic scale — one pH unit is a tenfold change.

How to practise it

Do questions, not chapters. Reading a physiology chapter produces a comfortable feeling of understanding that vanishes under exam conditions. Answering fifteen questions and reading the explanation for every one — including the ones you got right — produces something that survives.
