AI examiner evaluation

Task Achievement / Task Response — Band 7.0

You have clearly addressed the prompt and maintained a consistent position throughout the essay. The ideas are relevant, particularly the examples regarding healthcare and technology. However, the development of these ideas is somewhat basic. To reach a higher band, you should aim to provide more nuanced analysis rather than just listing examples. For instance, when discussing science as a tool for knowledge versus a tool for improvement, you could explore the ethical implications or the long-term necessity of basic research. Overall, the response is well-structured and directly answers the question.

Coherence and Cohesion — Band 7.0

The essay is logically organized with a clear introduction, body paragraphs, and a conclusion. Each paragraph has a central theme, and you use basic cohesive devices like 'firstly', 'secondly', and 'in conclusion' to guide the reader. However, the flow between sentences can feel a bit mechanical. To improve, try to use a wider variety of linking words and ensure that referencing (e.g., 'these developments') is used more precisely to connect ideas across sentences. Paragraphing is used appropriately, which helps the overall readability of the text.

Lexical Resource — Band 6.5

You demonstrate an adequate range of vocabulary for the task, using terms like 'scientific discoveries', 'public health', and 'global problems'. However, the vocabulary is somewhat repetitive and lacks the sophistication required for higher bands. There are also minor issues with word choice, such as 'clear energy' instead of 'clean energy'. To improve, focus on using more precise collocations and less common lexical items. Expanding your vocabulary to include more academic synonyms will help you express your ideas with greater precision and style.

Grammatical Range and Accuracy — Band 6.5

You use a mix of simple and complex sentence structures, but there are frequent errors in basic grammar, particularly with capitalization (e.g., 'science' at the start of sentences, 'i' instead of 'I') and article usage. While these errors do not impede communication, they are persistent throughout the text. To achieve a higher score, you need to demonstrate better control over punctuation and sentence construction. Try to vary your sentence length and ensure that subject-verb agreement and articles are used correctly in more complex structures.
