No, I think you're right. It will only look at the first cell in the range.
Array entering gets rid of the #VALUE! error, but doesn't actually get it to
use the full array. It isn't clear, of course whether the OP wanted OR or
AND to apply to his range and his conditions.

Perhaps you meant to do something like this
in say, IT27, copied down:
=IF(IS27=30%,"R",IF(IS27=20%,"A",IF(IS27=19%,"G ","")))
Test and modify to suit

I'm not sure that your expression is valid/works even with array-entering

Apologies:
=IF(IS27:IS3130%,"R",IF(IS27:IS3120%<29%,"A",
IF(IS27:IS3119%,"G","G")))

IS27:IS31 is the range where the data is in.
