Is 100 in english still possible?

Alr so I have done the syllabus, and I just am revising rn. I got 67/80 in boards, which were also the highest in my batch, so my teachers obv cut unnecessary marks. I'll do some grammar and literature pyqs. Is all this enough?

Also are there any last-minute tips, do's during exams, or anything regarding presentation. Please, I really need this centum.
