Cathoven analysis of the same Task 2 essay: Band-score estimate: 6.0 Per-criterion breakdown: - Task Response: Band 7. You answered both parts of the prompt and supported each with examples. This is your strongest area. - Coherence and Cohesion: Band 6. Each paragraph has a topic sentence, but linking between paragraphs uses the same connectors throughout (3 instances of "Furthermore," 2 of "In addition to that"). Inter-paragraph relationships need stronger signposting; some sentences within paragraphs jump between ideas without connection. - Lexical Resource: Band 6. Topic-appropriate vocabulary present but limited variety: "important" used 5 times, "people" 8 times, "communication" 11 times. No collocations or less common alternatives. Examiner descriptor at Band 7 requires "less common" lexical items used flexibly — your essay has none. - Grammatical Range and Accuracy: Band 5. Almost all sentences are simple or compound. Two attempted complex sentences contain comma-splice errors. Conditional structures (if/were/would) absent entirely. Band 6 needs "a mix of simple and complex sentence forms"; you're at simple-only. The descriptor holding you back from 7: Grammatical Range. Even if Lexical Resource jumped to 7, the rubric averages and your grammar would drag you back to 6.5. The 3 most impactful edits: 1. "It is important that people communicate" → "It is essential for individuals to maintain effective communication" (lexical + simple-to-complex) 2. "Furthermore, technology has changed how we talk" → "What is more striking is that technology has fundamentally reshaped the way we communicate" (varied connector + complex structure + lexical) 3. "If we use phones too much, we don't talk to family" → "If we became overly reliant on phones, we would inevitably distance ourselves from those closest to us" (proper second conditional structure) One sentence you wrote that's already at Band 7: "Although digital tools have widened our reach, they have arguably narrowed the depth of our conversations." Keep this rhythm of contrast — it's working. Estimated time to move from 6.0 to 7.0 with focused daily practice: 6-10 weeks.
