For AIIMS concepts are very important and as well as it's application and practice. Read NCERT first and make your concept clear first. HC Verma is a very good book to build a strong base in physics. Read the book and solve problems.

Another book i always recommend is physics for medical aspirants by Dc pandey (arihant publications) very good book,conceptual ,a lot of solved questions and previous year questions also there. I also recommend to buy a previous year physics question book by arihant publications where they give chapter wise questions of all medical exams. Take as many mock tests as you can before appearing in the final examination.

All the best !

Well, the level of physics is quite basic. If your concepts are clear, then it would be easier for you to crack. But also,  there will be some tricky questions too. It all depends upon your preparations. Do prepare yourself with all levels of questions.

Any book will do with a lot of questions. For phhysics is all about concept and practicing.

Refer to previous years question papers. You will get books also containing question papers from previous years.

Thank you.
