Worried about predicted grades

I have my Year 12 mocks in a week. They got delayed due to corona. I am a bit worried about my predicted grades. Biology has been really hard to teach myself over this lockdown period. I think overall I might get a C? I have been doing quite well in the year though, a mixture of A/B grades. My question is if I get a C is it likely I will get a B prediction? I HAVE to get a B predicted grade as I am retaking and can't afford to do a gap year if I don't get this grade. I have heard that in some cases teachers predict a grade up, or what you need but my biology teacher is quite strict so I am not sure.

If you get a C then you’re capable of a B for sure, just ask your teacher

Just do your best and even if your predited grades aren't quite what you would like them to be, you can still apply to unis asking for slightly higher grades than you are predicted. However, if you don't do so well in your mocks I would encourage you to apply to some "safe" uni choices that do match your predicted grades as well as a couple of more aspirational ones.
