Revision that works
How do I go from a 4 to a 6 at GCSE?
Two grades is a real jump and a common one. A 4 means the core is mostly there; a 6 needs that core automatic, plus the next layer of application on top. The work is not trying harder at everything. It is closing the topics that sit between those two grades, with question practice slightly harder than comfortable, most days, for months rather than a heroic fortnight.

What a 4 already gave you, and what a 6 still needs
A 4 is a standard pass. The basic methods are largely in place, even if they wobble under time. A 6 is the grade that starts to look like fluency: you still drop marks, but the routine questions are no longer where they go, and you can finish a paper. The gap between them is not secret content. It is speed on the easy marks, and enough of the next-harder questions that a typical paper lands you above the 6 line rather than scraping a 4 or 5.
Find the layer in between, then live there
Take a marked paper (a mock is perfect) and ignore the questions you got fully right and the ones that were hopeless. The middle pile - started, partly right, ran out of method - is the 4-to-6 layer. Those topics, practised until the method is automatic, are how the grade moves. In maths that is often rearranging, simultaneous equations, ratio, and the first stretch of higher-only content if you are on that tier. In written subjects it is usually the difference between a point-and-example answer and one that explains, in order, with a judgement at the end.
Climb the difficulty only when the current level is fluent. Jumping straight to the hardest questions on a 4 is how students decide they cannot do a 6. The 6 is the 4, done faster and more completely, plus a band of questions you are currently almost getting.
A timeline that is honest
From a solid 4, a 6 in one subject is a Year 11-shaped project if you start in the autumn: short sessions most weeks, pointed at that middle pile, with a full paper every month or so to check the line is moving. After winter mocks the same jump is still on, because the mock is a fresh map. From Easter it is possible in one or two priority subjects and unlikely across the whole timetable. Spread the ambition too thin and you keep the 4s.
Maths, sciences and the written subjects are different climbs
In maths and the calculation side of science, the 6 is mostly fluency: more of the paper finished, fewer dropped method marks, the next topic up becoming routine. Question practice is the whole job. In English, history, geography, RS and business, the 6 is a writing habit: answers that always use the text or the case, always explain, and on the longer questions actually conclude. You cannot highlight your way into that. You write, you compare with a mark scheme, you write again.
