Why this happens to doctors

Agreement slips happen when other words come between the subject and verb. They are small errors, but they appear in every paragraph for many candidates and limit the accuracy score.

Why this affects doctors: medical writing favours dense, technical sentences, which can read as over-compressed in general-topic essays.

Long nominalised sentences invite comma splices and agreement errors.

A strength to build on: Training in evidence-based reasoning is a real advantage for building and supporting an argument.

Fix it in four steps

Underline the subject and verb of each sentence in your essay.
Cross out any phrase between them and check the verb matches the subject alone.
Remember: the number of is singular, a number of is plural.
Check each 'there is' or 'there are' against the noun that follows.

Before and after
