More topic words wanted. What does this mean?

'topic words' means some words are shared by all users. for example, 'technology', 'device', 'communication'. Those words may appear in a lot of essays.

Now suppose those words appear in your essays too, the e-grader will be happy to see them and give more credits. But if the e-grader can't find those 'topic words', it will ask 'More topic words wanted.'

This doesn't mean your essays are developed wrongly, while there are some reasons causing this: for example, the essay topic is something new with few users developed it before, like the topic you mentioned:

Biotechnology companies all over the world are developing different types of genetically modified (GM) crops. ...

few essays will deal with 'Biotechnology', 'modified (GM) crops' .....

so if you have this message 'More topic words wanted.' in other of your essays too, then it could be a problem, if it comes only in this essay, then it is not a problem.

-------------------------

if the e-grader asked more 'neutral topic and sentences'. most likely you don't develop enough content. In task I, We are expecting:
No. of Words: 175 while No. of Different Words: 100

in task II, We are expecting:
No. of Words: 350 while No. of Different Words: 200

------------------------

Since e-grader can't understand the meaning of the words or ideas, it will judge the score by your language like: words, sentences, coherence...

Hi,
Thank you for the detailed information.
The meaning of 'Different words ' is the replaceable words?
Does this mean that e-grader only counts the differences between number of words and the different words within the essays in order to score the essays?

Thanks,

'Different words ' means Unique words in one essay. For example, in the sentence: 'People are people.' The total words: 3, while 'Different words': 2.

The e-grader will judge an essay by following attributes all together, not depend only on words, if any one attribute is too high or too low, the e-grader will give the warning messages, and they will affect the final score. There are over 50 attributes:
