Dear student,

If you want to get complete marks in the Coordinate Geometry portion, then your basic concepts must be clear. Follow some good books . Some best books for coordinate geometry are listed below.

Coordinate Geometry by Cengage

Coordinate Geometry by SL Loney

Alongwith these books, you must solve previous year papers of JEE. Solving previous year papers and mock tests, will be very beneficial for you, not only in the coordinate part but also in the whole exam.

Hope this helps.
