The DET uses two grading methods: automatic grading for fixed-answer questions and AI-based grading for open-response tasks. Here's how they work
1. Automatically Graded Questions
Questions like Read and Complete, Read and Select, Fill in the Blanks, Listen and Type, Complete the Passage, Highlight the Answer, Identify the Idea, and Title the Passage are graded automatically using advanced algorithms. These algorithms compare your answers to correct responses and measure how close your answer is.
Key Points to Understand:
- No extra penalty for wrong answers: If you skip a question or provide an incorrect response, you will lose the same amount of points.
- Partial credit is possible: Even if your answer isn't completely correct, you can earn partial points. For example:
- Tip: Always attempt to answer every question, as trying gives you a better chance of earning points.
2. Open-Response Questions
Tasks like Summarize the Conversation, Write About the Photo, Speak About the Photo, Interactive Writing, Interactive Speaking, Read Then Speak, Writing Sample, and Speaking Sample require open responses. These answers are evaluated by an AI-based grading system that works similarly to human experts in assessing English proficiency.
