Co ordinate geometry is quite a vast topic.
It takes around 3 months time to completely cover all topics listed and to solve an average number of problems from all portions.
Conic sections are new topics, and they have a lot of similar, but confusing equations.
Stright lines and 3 dimensional geometry are relatively fine portions.
If you wist to rush through them, without solving much problems in classes, then you can do it in 2 months or less.
