Question 1

Leaving a final answer line blank of its unit in moments and stability calculations, despite the answer line explicitly prompting 'Unit ='.

Accepted Answer

Treat the unit as its own separate mark. Write it the moment you write the number, not as an afterthought.

Question 2

Writing a 6-mark QWC answer that covers only part of what the question asks, for example describing metallic bonding without mentioning delocalised electrons, or missing a required stage of a biological process.

Accepted Answer

Before writing, list every part of the question in the margin and check the finished answer touches each one before moving on.

Question 3

Forgetting to convert minutes to seconds in power calculations using $P = \dfrac{W}{t}$, which introduces a factor of 60 error into the final answer.

Accepted Answer

Convert time to seconds as its own written step immediately after reading the question, before you touch the formula.

Question 4

Confusing the roles of insulin and glucagon, or misidentifying which organ, the pancreas or the liver, is responsible for a described hormonal response.

Accepted Answer

Learn insulin and glucagon as a pair with opposite effects on blood glucose, and name the pancreas as the organ that releases both.

Question 5

Using mass directly in a force or pressure calculation instead of first converting it to weight, forgetting to multiply by $g = 10\,\text{N/kg}$.

Accepted Answer

Whenever a question gives mass but the formula needs force, calculate weight as its own step before substituting anything else.

Question 6

Omitting state symbols in a balanced or ionic equation when the question specifically asks for them.

Accepted Answer

Once a question says 'include state symbols', add one to every species, including (aq) for dissolved ions and (l) for water, not just the ones that feel necessary.

Question 7

Believing plant cells burst when placed in pure water, rather than explaining that the cell wall creates turgor pressure that resists the cell bursting.

Accepted Answer

State explicitly that the cell wall, not the cell membrane, is what stops a plant cell bursting in a dilute solution, and name the resulting pressure as turgor pressure.

Question 8

Failing to round a final numerical answer to the degree of precision the question specifically asks for, such as one decimal place or a whole number.

Accepted Answer

Underline or circle the precision instruction the moment you read the question, and check the final answer against it before moving on.
