What comes next
What grades do I need for sixth form - and what if I miss them?
Most sixth forms ask for a spread of GCSE passes - commonly grades 4–5 across five or so subjects, with a 6 or higher in anything you want to study at A-level. Selective sixth forms ask for more. The only list that matters is the published requirements of the places you apply to, not a general rule. Miss them on results day? Talk to them that morning - flexibility is more common than the prospectus suggests.

What sixth forms typically ask for
There is no national entry requirement for sixth form - each one sets its own, so treat anything below as the shape of the thing, not the numbers for your case. That said, the shape is consistent: a general bar (a handful of standard passes, usually including English and maths) plus subject-specific grades for each A-level you pick. The subject grades are the ones that actually bite: a 6 is a common ask for essay and science subjects, and maths often wants a 6 or 7, because A-level maths builds directly on the top end of the GCSE.
Selective and high-performing sixth forms ask for more across the board - sometimes mostly 7s. That is about managing demand for places, not a judgement on what you need to succeed at A-level. Wherever you apply, find their published requirements page and write down the exact grades next to each subject you want. That list is your target, in black and white, months before the exams.
If you miss the grades on results day
This is the part nobody tells you in advance: entry requirements are firmest on paper and softest on the morning of results day. Sixth forms plan for a spread of results, places open up when other students' plans change, and a near-miss with a good story - strong grades elsewhere, a clear reason, obvious commitment - is very often workable. So if the envelope is not what you hoped, do not quietly cross the sixth form off. Phone them or go in that morning, results in hand, and ask what your options are. The students who ask often get somewhere; the students who assume the door is shut never find out it wasn't.
If it genuinely is a no, the road forks rather than ends: the same A-levels run at other sixth forms and at FE colleges (often with different entry asks), a college can pair a course with an English or maths resit, and vocational routes like BTECs and T-levels take you forward just as surely. Missing one set of grades changes the route, not the destination.
Pick a target and a backup - on purpose
Apply to more than one place, and make the spread deliberate: a target you would love, whose requirements stretch you, and a backup you would genuinely be happy at, whose requirements you are comfortably clear of. Visit both - open evenings tell you things a website cannot - so that if results day sends you to the backup, you are walking into somewhere you already chose, not somewhere you fell into. Most sixth forms are entirely relaxed about you holding offers elsewhere; it is the normal way to do it.
