German reading grade boundaries??

I just did a German reading past paper (AQA June 2018) (recommended by my school) within timed conditions. I got 40/60 which is I think 66.66%? I'm really shit at listening and reading tbh, I mostly rely on writing and speaking not to fail 😓😓😓

Does anyone know what grade this would be/if it's a 7??

I'm currently on a grade 7 with German (occasionally a grade 8)- so far we have done our writing mocks and listening mock and I am on a high 7!! Tbh I'm quite happy with that result (even though some might find it a bad grade 😓) and I just want to like stay on this level so I can focus on improving other subjects.
