I would advise you to consider Arihant Previous Years Book for PCM JEE Main & Advanced. It has a total collection of 42+Years Questions across IIT JEE and Mains. However after JEE Main, youre first primary previous year guide should be Disha Target JEE Advanced Previous Year Paper Book. From my experience this book had answers in more details besides Yearwise Question Papers from IITJEE 2005-Current Past Year. Solve DPP Regularly and try completing syllabus on time besides analyzing your Test Series and checking out your weaknesses and test taking strategy.
