My DD missed most of 6th form due to illness, only took one A level, but managed to put together a good personal statement and with only 34 UCAS points got several unconditional offers for Foundation years in fashion (she has never been well enough to go in the end but that's not relevant to this post). Before she applied anywhere, I rung the admissions team at each uni she wanted to apply for, went through the issues she was having, not enough points etc., and got a lot of really good advice for her.
My older DD had some problems with her college, luckily she also had unconditional offers although in the end she would have got in anywhere on her grades. But she told me that those students whose parents didn't understand the UCAS system were just left floundering by the college (wonder if this is more prevalent in colleges than schools).
Its ENTIRELY reasonable to expect the college or school etc to handle this - its essential they do the work required, its not an optional "extra". However, it is also essential that a parent knows when the college isn't supporting applications so that the parent can step in and help - just as if your DD wasn't doing the application properly, you'd help them - theres a formal process to be followed. What about kids without parents, those in care, or whose parents DGAF? The buck definitely stops with the colleges/schools etc.
But now you know OP, so if you can get a meeting with the college then do so and ask them to whole-heartedly support your DD. As previous posters have said there are plenty of options and I see early on in the thread a poster said they'd worked as a UCAS adviser and offered a DM. Good luck to you and DD.
