Hi,
I am applying to 9th grade in a few prep schools and am worried about my grades in 6th grade. You see, in sixth grade I wasn’t really paying attention to my grades and messing around when I somehow got a B. 
In 7th grade, I started thinking about going to prep school, and my grades are all As there. Will this hurt my chances in big, prestigious prep schools a lot?
No it will make no difference whatsoever!
From what I have seen they don’t ask for
6th grade grades.
Only on CC does B=bad. A B is a fine grade. Let it go.
All BSs my DD applied to asked for grade 6-8 transcripts. Her 6th grade grades weren’t stellar. It mattered none for admission.
Alright, thank you for the helpful advice everybody! I was quite nervous about this.
@flamestorm This is a little late but tbh a couple bad grades wouldn’t affect ur application that much. I had a couple Bs and gasp a C in my seventh grade year and still managed to get in.
