Bro it happens to us all.
I've been having reports covered in red, negative comments, stupidly unrealistically low predicted grades, and even emphasised teachers comments for years. 7 Years to be exact.
Everyone around me always had perfect reports, yet guess who, after all that, was the only one to get an Oxbridge offer...
Ignore them. Reports means nothing, it's a schools way of motivating you. They don't actually mean anything. You can tell as usually different teachers will give you different report scores, despite you putting in the exact same effort, and scoring the same, in both subjects. Schools are stupid, but that's only because "those who cannot do, teach".
