I practiced this essay and faced some conflicts. So I partially agree and wanted to present a balanced view, however in writing I had a lot of points, for both positives and negatives in mind and considering word limit, I was not able to elaborate properly.
It is not about examiners understanding. It is about showing a range of vocabulary. If you pack an essay with high level medical words, but the rest of your vocabulary is only average – the examiner will easily see you do NOT have a wide range of words. The examiner will see you are a doctor and your vocabulary is limited to medical English. This means your vocabulary score will not increase. You can’t cheat IELTS. You need to show a range of vocabulary from all topics – not only medical language. So, don’t full your essay with medical vocab – it won’t help.
What Does The Essay Word Limit Really Mean?
A few words over or a few words under the 300 word limit is not concerning to the review committee. If you are 100-200 words over the limit the essay is too long and the reviewer will likely just stop reading. We aren’t counting each word but we have a pretty good idea what 300 words looks like.
