A Level on UCAS

I got a U in Biology in 2016 but the overall grade was not shown. I resat this and in 2017 I achieved a C in Biology, but the overall grade was not shown, how do I enter this on UCAS as I put down the U and C which may have been a mistake

Did you put the U for the appropriate modules then enter the modules again and put a C?

I put down the overall grades without any modules

So a U then a C?

Sort of like this
GCE Advanced Level
Biology C 06/2017 AQA
Biology U 06/2016 AQA

(The overall grade wasn't shown on my results sheet though)

Yes do that

Would there be any issues as I believe these grades were not certificated/cashed in?

I believe it wouldn't be certificated any way as a U gives you no qualification technically

What about the C I obtained from resitting?

You should have got a certificate for that.

I never recieved a certificate for the C in Biology as it was not cashed in and an overall grade was not shown on my results sheet
