how can i study for jee from scratch if i'm only appearing for the 2nd session within a month?

Dear student,

First thing is be calm and make a good study plan or schedule which can be followed during one month. Accordingly i am suggesting to atleast give 3 subject sufficient time to learn and practice.

First cover the Important and easy to cover and solve PYQ with the theory only , try to complete maximum syllabus in one month and revise old in free time ( reading short notes etc.).

Do this in all three topics and in one month you will be good at basic problem and as you have solved the previous year question you can get an idea of moderate level questions too.

Cover all the 3 subject equally don't leave any subject completely, it can have disadvantage in exam if question paper come easy from the subject you haven't study.
