Can I still get 90%+??

I am in 10th, I scored way lower then I expected in preboards...

Maths: 48/80

English: 62/80

Science: 61.5/80

Hindi: 63.5/80

Sst: 67/80

Total 75% (itne kam aaj tak nahi aaye...) Sad part is mujhe actually laga tha mere exams ache gaye hai (except maths) ... And now idk what to do...

6 jan se preboard 2 hai 🥲
