Writing topic breakdown

Moving from 6.5 to 7 depends on repairing the bottleneck.

Turn topics, samples, materials, or prediction prompts into task reading, development, examples, and revision steps first. The goal is not memorising answers; it is writing your own next version.

A topic page is useful when it helps you write your own next version.

Common mistake

Treating all four criteria evenly diffuses repair and leaves the main blocker unchanged.

Diagnostic evidence

If every feedback mentions the same issue type, that is the priority revision target.

What to confirm before writing

Put the main blockers from the last three essays side by side.

What to revise in the next version

Choose the most frequent criterion and verify evidence change with same-prompt rewrite.

Four typical profiles stuck at 6.5

Profile one (most common): language largely clean, but every argument is claim plus example with the mechanism sentence missing — TR 6 drags the average. Profile two: full arguments but in-paragraph jumps, patched with Firstly/Moreover — CC 6. Profile three: ambitious vocabulary with high collocation error rate, low precision — LR 6. Profile four: error-free simple sentences, but clauses fail more often than they succeed — GRA 6. Each profile needs a different repair, so identify your profile first; "write ten more essays" just reinforces the existing habit.

Worked example: repairing a 6.5 development chain to 7

Original: "Public parks improve mental health. Many studies show this. Therefore cities should build more parks." The grammar is fine; what it needs is a mechanism between assertion and conclusion. Repaired: "Public parks improve mental health because they offer the only no-cost space where city residents can exercise and meet neighbours daily. Regular users report lower stress in most urban surveys. Given that a single park serves thousands of nearby residents, expanding them is among the cheapest public-health tools a city has." One repair move only: after the claim, answer why it holds and through what path. This is the highest-frequency single fix from 6.5 to 7.

Why volume practice stops working at this band

Before 5.5, volume genuinely raises scores because the bottleneck is fluency. Past 6.5, the bottleneck becomes one or two specific habits: missing mechanism sentences, one recurring clause error, incomplete position coverage. Undiagnosed repetition makes those habits more fluent. The loop that works at this band: identify your profile, repair that single point, verify with a same-prompt rewrite, and only move to a new prompt after the evidence shows change.

The real cost and timeline of half a band

Moving 6.5 to 7 usually takes lifting one criterion from 6 to 7. With the loop above, one blocker typically takes 2–4 same-prompt rewrite rounds: two to three weeks of targeted work, a far better deal than another three months of prompt grinding. The risk is direction: repair the wrong blocker (profile one memorising a word list, say) and the time is fully wasted. That is why diagnosis precedes practice.
