My son has poor working memory and slow processing, which meant basically the lessons were being delivered too fast for him to process, and most of it went over his head, which is probably the same problem your daughter has in lessons.
So you need to know how they are going to make the lessons accessible for your daughter and what support they are going to put in place.
You could ask for an EP assessment as they will be able to give the school advice on how to meet your daughter's needs, although they don't have to agree to do this.
Basically my son had a TA or other adult with him in class most of the time who repeated what the teacher said, explained things in more simple terms, broke down instructions one at a time and allowed him time to process questions before expecting an answer from him.
He also had written instructions taped to his desk so he knew what he had to do each morning, and the (good) teachers included visual stuff in lessons which helped understanding and learning.
I suspect the school will tell you they won't be able afford a TA in which case you could ask them to support you in applying for an EHC Needs Assessment.

What sort of progress has your DD made so far? Is she behind the rest of the class?
Does she have speech and language therapy?
