Hello akhil

I Hope you are doing fine

I would firstly  want to say their is never late if someone has will to persue something, then age is just a number. But yes at your level you need to work really very very hard with pure consistency with atleast 8hours per day . Try to make a proper roadmap and covers sections which have easy topics and come frequently in exam . First try to cover reasoning and quant for which unacademy will be the best source and practise 10 years questions on them. Dont stick to particular sections , divide the day in three halfs for each sections . For maths ,dont go for coordinate and prepare integral calculus as much as possible

Hope you found this answer helpful. Good luck for your future
