Dear Aspirant,

Well, frankly JEE Advanced is a tough exam as compared to JEE Mains. Many students struggle to score in this exam. Physics is tougher. But I want to tell you that with the right strategy you can get the required marks to grab your seat in the IITs. Strengthen your core concepts of chapters. Don't try to attempt all the questions. Focus on your accuracy. So, no I don't think it will be difficult for you if you study smartly.
