Band 4+: Nowadays artificial intelligence is being used to drive cars. Why is this happening? Is it a positive or a negative development?

The essay addresses all parts of the prompt. You have identified a reason for the rise of AI driving (technological advancement/big data) and provided a clear position that this is a positive development. You also supported your position with two main points: safety and time efficiency. To improve your score, focus on the following: 1. **Depth of Development**: While you mention reasons and benefits, the development is somewhat superficial. For example, in the second paragraph, you explain *how* AI learns, but you could more explicitly link this back to *why* this is causing the widespread adoption of self-driving cars in society. 2. **Cohesion and Coherence**: Some transitions between ideas are abrupt. Using more sophisticated linking words would help the flow of your arguments. 3. **Precision of Ideas**: In the third paragraph, the point about 'fear of accidents' is a bit vague. Instead of focusing on the driver's fear, focus on the *reduction of human error*, which is the scientific reason why AI is safer. 4. **Grammar and Spelling**: There are several typographical errors (e.g., 'artificail', 'advancment', 'manully', 'viechle', 'utlize') and grammatical slips (e.g., 'it's now able', 'million of data', 'have arrive earlier'). While these do not prevent understanding, correcting them will improve the overall professional quality of the writing. The essay falls short of the required 250 words.

The essay follows a logical structure with an introduction, body paragraphs, and a conclusion. However, the progression of ideas is sometimes interrupted by sentence fragments (e.g., 'Meaning software does not have to be programmed manully') and abrupt transitions. To improve, ensure that every sentence is a complete thought and use a wider variety of cohesive devices beyond 'Moreover' and 'Also' to link ideas more smoothly.

The vocabulary used is sufficient to convey the main ideas, but there are frequent spelling errors (e.g., 'Artificail', 'advancment', 'manully', 'viechle', 'utlize') and repetitive phrasing. To reach a higher band, aim to use more precise academic vocabulary and ensure that spelling is accurate. Try to avoid repeating the same words (like 'fast development') by using synonyms such as 'rapid evolution' or 'technological breakthroughs'. Boost vocabulary complexity to elevate the overall score.

There are significant grammatical issues throughout the text, including subject-verb agreement (e.g., 'it save', 'it reduce'), incorrect pluralization (e.g., 'million of data'), and issues with article usage. There are also errors in tense and sentence structure. Focus on mastering basic sentence structures and ensuring that singular/plural nouns match their corresponding verbs. Practicing the use of complex sentences with correct punctuation will also help improve your score.
