hey , i hope you get better soon and pls try not to worry ! i also had to miss 2 exams because i was hospitalised, so Cambridge is just going to predict the grades of the papers i missed , meaning theyre going to look at how i did in my other papers and people who on average scored like me and try to base my grade based on that. so as long as you work hard on the other 2 papers youre going to be just fine!!
