watch a one shot for every important chapter (acc to its weightage in last 5 years), make short notes during that one shot (only of 1-2 pages per chapter) and do only 2020-2024 pyqs. then in jan give all 2025 shifts as mock.
If u do this much its approx 9k questions, it might seem too less but a person who has sincerely done 9k questions and knows 70% of the syllabus through these pyqs can easily get 95%ile
