Mathematics 12 by R D Sharma is a very good book for the concepts and practice material including a lots of solved questions with proper explanation. If you have done a chapter, the Together With Maths is very good to get proper practice. Just like R D Sharma, All in One for Mathematics is also very good book with ample practice questions. CBSE Mathematics ( 15 Sample Question Papers ) is very useful after going through whole syllabus.
