Preparing for JEE Advanced Physics can be a daunting task, but if done correctly, it is the most enjoyable subject ever as it blends maths and science beautifully. I would recommend to to solve all the solved examples of all the five books of the DC Pandey series. Solving these will give you the required confidence and will boost your morale.

Once you are done with Pandey series, pick up Physics Galaxy by Ashish Arora and go through all the solved examples, this will prepare you for Advanced. If you have time left, then also solve the exercise of PG book. Hope I have answered your question. All the best!
