HELLO,

From zero level a student might reach 70 to 80 percentile in JEE Mains with intense, smart one-month prep by focusing heavily on high-scoring areas like Inorganic Chemistry (NCERT), key Physics concepts , easy Math chapters, and consistent PYQ practice, but a 95+ percentile is challenging and requires immense dedication, speed, and strong fundamentals, with success heavily relying on mastering core concepts quickly and practicing mock tests effectively

Hope this Helps!

Hello dear aspirant, to be very honest it depends on your hardwork , if you put in each second of that month you can get even to 80-90 percentile or if not practiced or revised much, you can be below 30 percentile as well so the choice is yours , without thinking of the time just put in all your effort and hardwork and see the result.
