Hello, I've just read a news on the BBC app and haven't made sense of the preposition "on" in this context as I've ever been taught that when mentioning a particular year, we use " in" such as in 2020, in 2021 ect.
Could you explain for me why the BBC journalist wrote like that ?
" The percentage of pupils achieving A to C grades in their Highers was 87.3%- down slightly on 2020"
source: A-level 2021: What you need to know about this year's results
Thanks in advance.
3%- down slightly on 2020 . It looks like the writer is comparing this year's grades (2021) to those of last year (2020) because "on" means "in comparison to". On the other hand, "on" may be a misprint for "in".

It's impossible to say from such a short
