Using Mixed Tenses in OET

Your answer will be made of mixed tenses. And it is important that you make use of the right form of tenses whenever you write. 

A small mistake in describing situations can create confusions. 

Consider these examples:

The patient doesn’t want to eat. (present tense)
The patient didn’t want to eat. (past tense).

If you use the present form to showcase things that happened in the past or the past form to show things of the present, it will create a problem for the readers. And in medical writings, it can create a big blunder. 

As you know, a verb may have different forms. And using the right form of verb in the sentence is necessary. Most of the grammatical errors occur only because of the use of the wrong form of verbs. 

Wrong Sentences (Bad Grammar)
