In order to prepare for JEE you must concentrate on both 11th and 12th class. Syllabus is based on both the classes and 12th class have more weightage. Ratio is not fixed but it can be 40% from 11th class and 60% from 12th class. You can take help of NCERT book to understand the concepts. You should be aware of the important topics so, you can give then extra effort. Refer previous year papers to understand the exam pattern and level of questions.
All the Best!!
I would suggest you to clear all your concepts of Physics, Chemistry and Mathematics of both classes 11 & 12. Make your foundation strong with the clarity of concepts. This clarity will help you in the preparation of JEE Main and JEE Advanced both.
