If you resit and get lower, do they use your past result for A-levels?

i'm resitting all my a levels this year and i was just wondering, if my grade last year was higher then my grade this year, would i be able to use whichever grade is higher for University? I've already applied this year and got my offers, but lets say for example for chemistry i did worse this year then last year but last years chemistry grade still met the univeristy entry requirements, would i be able to use my original chemistry grade but my new grades for my other subjects? like would universities still accept that? thank you

Hi I was told that if I sat my chemistry exam this year (year 13) then I would have to give it up to resit it next year (year 14, but year 13 in my other two subjects) but I would still have to say what I'd achieved in both scenarios.

For example, if next year I got BBB but this year I had gotten an A in my chem then I would still apply to unis with my BBB but they would be aware that I had gotten an A previously but it wasn't my final grade if that makes sense.

My teachers might have gotten it wrong so I'm not entirely sure but as far as I'm aware you can't choose the higher grade but the uni will be able to see both grades. I hope that helps
