I've received my Yr 12 Mock results and I don't know how to feel

I sat my mocks for bio, psych and Law recently and got my results back. 3 C's. For bio that's an improvement as I was failing before but for law and psych I've gone from getting B's, A's and A*'s. This is my first year 12 Mock so there's definitely room for improvement. What I want to ask is are my grades bad? Do I have no hope in being predicted AAB? Lots of people I know have gotten top grades and it feels like Im very behind. I do have a plan tho. I will work hard for my unit assessments to prove to my bio teacher that I'm capable of getting a B at least. And I'll show my Law and psych teachers that I've been getting A's and A*'s in the past so this is just a one off. Despite this plan my parents are very disappointed in me. You could say their the strict type. Their not happy with my grades and I don't think they really listened to my plan. I was feeling alright about my grades before but after hearing all this I've become disheartened and I'm losing hope in my future. What are your honest opinions?
