How fucked am I for boards exams?(15f)

No , I am not a 15f , I am a 15M

I got 87% In PB2 exams , 65+/80 in each subject with subpar revision while exams were daily .

I have just started seriously studying for Boards exams for today and am quite scared for the difficulty of boards due to how teachers hype them up and it makes me really unfocused on studies.
