The AI Score-Killer Checklist

If you use these 3 patterns, the AI will immediately flag you as a “low-level” speaker:

• Repetitive Starts: Starting every sentence with “I think…” or “There is…”
• Vague Vocabulary: Overusing words like “good,” “bad,” “nice,” or “stuff.”
• Short Simple Sentences: Writing like a 10-year-old (Subject + Verb + Object).

1. My Experience: The “Good” Sentence Trap

In my opinion, the most dangerous mistake is being “too safe.” When I first started, I wrote perfectly correct but boring sentences. However, the AI saw this as low proficiency. Indeed, a sentence like “The weather is good and I like it” is grammatically correct but will never get you a 120+. To improve your Efficiency, you must replace these with complex structures like “The favorable weather conditions significantly enhance my mood.” This level of AI-Powered Mastery is what recruiters look for in Career Growth.

2. [Prompt Copy] The AI Sentence Auditor

To avoid these TOP 10 mistakes, you need a coach to find them. Thus, I’ve designed this ChatGPT prompt to act as a “Score Killer” auditor. Simply drag and copy the text below to refine your writing.

[Prompt Copy]
“Act as the Duolingo English Test (DET) AI Grader. I will provide a response.

1. Identify if I used any of the ‘Top 10 Sentences AI Hates’ (e.g., repetitive structures, vague words, simple sentences).
2. For every ‘hated’ sentence, provide a 140-score level alternative using advanced collocations.
3. Audit my ‘Lexical Sophistication’ and suggest 3 academic synonyms to boost my Efficiency.
4. Give me a predicted Production subscore based on this response.
   [Insert your response here]”

Notably, this prompt helps you identify bad habits that are invisible to you. Consequently, you build the AI-Powered Mastery needed to impress the actual test algorithm.

3. The Path to Professional Career Growth

Why should you care about what an AI thinks? Clearly, the ability to avoid “lazy” sentences translates directly to professional success. Whether you are writing an email to a CEO or a university application, Efficiency and sophisticated English are key. Therefore, treating the DET as a training ground for your Career Growth is the best mindset you can have.

Conclusion: Stop Being Safe, Start Being Sophisticated

Ultimately, the Duolingo AI rewards those who take risks with complex grammar and academic vocabulary. So, stop using those TOP 10 “hated” sentences and start using the patterns I’ve shared. Resultantly, your score will jump, and your confidence will soar. Your journey to 130+ is about working smarter, not harder.

Think of collocations as the “secret sauce” that makes you sound like a native speaker rather than a walking dictionary. I’ve put together the ultimate list of 50 high-level collocations that will level up your Writing and Speaking responses instantly.

Why Collocations are Your Ticket to 130+

In the DET, the “Lexical Sophistication” and “Grammatical Complexity” scores are heavily influenced by how naturally you combine words. Using “drastic change” instead of “big change” tells the algorithm you have a nuanced command of English.

The “High-Scorer” Collocation List (Sneak Peek)

Here are some heavy hitters from the full PDF list. Practice integrating these into your practice sessions:

1. Academic & Professional Contexts

• Adhere to (rules/standards): “Students must strictly adhere to the university guidelines.”
• Mitigate issues: “The government implemented new laws to mitigate the environmental impact.”
• Bridge the gap: “Innovative technology helps bridge the gap between different cultures.”

2. Expressing Opinions & Impact

• Strongly advocate: “I strongly advocate for the implementation of green energy.”
• Vastly overrated: “In my opinion, the importance of standardized testing is vastly overrated.”
• Profound influence: “Social media has a profound influence on modern communication.”

3. Describing Trends

• Exponential growth: “The tech industry has seen exponential growth over the last decade.”
• Steady decline: “There has been a steady decline in the use of traditional mail.”

How to Use This List for Maximum Impact

Don’t just memorize them; contextualize them. When you’re doing the “Write About a Photo” or “Interactive Writing” tasks:

1. Identify the theme: Is it about society, tech, or education?
2. Pick 2-3 collocations: Don’t overstuff, or it will look forced.
3. Check your prepositions: Collocations are only effective if the “connector” words (like to, with, of) are correct.

Pro Tip: Print the PDF and stick it next to your monitor. Every time you do a practice test, try to “strike through” at least five collocations as you use them.
