Hello Ganigani

Syllabus is not much different of AP state board from jee but

• Detailed study of the syllabus required for jee
• Those topics you study in class 11,12 is completely similar to jee but there will more and more questions for practice
• And jee requires the master study of every small assumption related to any topic

JEE Main and JEE Advanced exams are more or less based on NCERT syllabus. The Andhra Pradesh State Board uses NCERT books for Physics & Chemistry but you should focus more on physics and chemistry as for state board the syllabus is a little easier compared to jee but maths with state board has a slight edge for you from state board

hope this helps you
