Band 7 vs Band 8: what actually changes
Put a 7 and an 8 side by side and the difference is not the error count. Both have errors. The 8 has things the 7 is missing.
The two scripts, compared
| Around Band 7 | Around Band 8 | |
|---|---|---|
| Task response | All parts answered, one of them thinly | Every part developed, position clear throughout |
| Organisation | Logical, with visible signposting | Logical, and you stop noticing the signposting |
| Vocabulary | Sufficient, occasionally imprecise | Precise: the right word, not the rarer one |
| Grammar | Complex sentences attempted, mostly controlled | Complex sentences used naturally, errors rare and minor |
Read the right-hand column again and notice how little of it is about avoiding mistakes. Range, precision, development. Three things you add, not three things you remove — which is why the usual strategy of hunting the last errors does not move anybody from 7 to 8.
Essays awarded 8 and above routinely contain slips: a wrong preposition, a missing article, an odd collocation. Essays that are almost clean are often awarded 7, and the examiner comments explaining why frequently do not mention accuracy at all.
Where 7.5 comes from
There is no Band 7.5 descriptor. A 7.5 is arithmetic: two criteria at 8 and two at 7 average to 7.5. So do 8, 8, 8 and 6.
That matters more than it sounds. If you are at 7.5 you are already at 8 in two criteria, so the efficient move is to lift the weakest one a full band rather than nudge all four. And it is frequently Lexical Resource or Task Response, not the grammar people spend their evenings on.
Work out your own split. If you have a scored practice essay, ignore the overall and look at the four criterion scores. The lowest is where the next half band is cheapest.
Four things that will not do it
Rarer vocabulary
Lexical Resource rewards precision, not obscurity. Ameliorate where you meant improve is a downgrade if the register is wrong, and examiners notice vocabulary that has been inserted rather than chosen.
More linking words
Putting Moreover and Furthermore at the head of every paragraph makes cohesion more visible, not better. Mechanical linking is a weakness in its own right — see what examiners actually reward.
A longer essay
No reward past the minimum, and padding adds errors without adding ideas. Detail in the word count guide.
A conclusion for its own sake
A conclusion restating the introduction in different words adds nothing. What lifts Task Response is a conclusion that follows from the argument. In General Training, an ending appropriate to the genre is fine; there is no required essay shape.
What will
- Develop the thinnest part. Most 7s answer every part of the question and give one part two sentences. Find it and give it a paragraph. Usually the largest single gain available.
- Keep the position visible throughout, not only in the introduction and conclusion. At band 8 a reader can state your view after any paragraph.
- Vary structure deliberately. Range means variety, not difficulty. Three long subordinate clauses in a row is not range.
- Replace the approximate words. Reread your own essay and mark every word that is roughly right. Those are the Lexical Resource marks.
One honest caveat
7 to 8 is harder than 6 to 7 and slower. Six to seven is largely about eliminating recurring error patterns, and that is trainable in weeks. Seven to eight is precision and development, which improve with reading and writing volume rather than with rules.
Anyone selling you the second step on a fixed timetable is guessing.
