Need Guidance, please reply if scoring 97-98+

Don't need copium or criticism ki nhi hoga. I have to touch 98.5-99 by any means by April. I wanted to ask what should i focus on now more. And how should i improve. 95%ile maybe is enough for math but how should i achieve it in 20-25 days from this(boards hai). I know theory of high weightage chapters except integ and functions. I want to push 99 in phy and chem. Please seniors and toppers batado kya aur kaise karna hai. Also 97-98+ bola as it will be helpful for all if advise comes from people who have done well enough
