Jee mains is not a subjective test but an obecobjec one and for that you need to know every thing from top to bottom thoroughly to get through with it. Just memorizing some topics which someone finds important is not enough for you to get a good score. So please you still have a month time for the preparation do it whiwh heardly and with a focused mind.

You'll surely get through

Best wishes

Thanks
