Hii Rahul,

In JEE mian  questions which are asked are combination of more than 2 chapters.

so if your luck will with you then may be questions wiil asked from only those chapters which you have read.

but there is also can bbe a scenario that questions will be combo of two chapters 1 from the read one nd other from the chapter which you didn't read.

so I advice you to altest give a look at every chapter.

thank you    

Hello Rahul!

Yeah it is possible and that is a nice move to prepare chapterwise. But if you are targeting 180 marks then your score will be as low as 100 or something. Yes you can preapare those 180 mark chapters first and then move to others if possible.

Hope it helps!
