Brother @Viraj i guess yu r clear with all the concepts in coordinate geometry!Yu might have already revised yur notes well many a time!
My advice to yu will be to make a separte revision notebook for maths.Now yu must start solving the imp problems that yu have encountered in yur 1st go..try to solve without help..if yu feel like yu r taking time to reproduce the approach for that partcular question..then yu must write down few imp points that are needed to crack that question.(Suppose if yu find a problem regarding homegenisation of parabola,then in the book yu can write down some links b/w the question and approach).Revise these notes regularly.
Also note that in jee advanced,many a time the same concept from previous years are repeated(not directly the question)..especially the subjective type..if yu have already solved archives then yu may go 4 a quick revision of the most imp problems and note down the problem solving tricks as well!!
Now use these notes regularly and try solving new problems..see if yu are able to recall more efficiently..also all the formulas of coordinate geo must be at yur fingertips..yu shouldnt waste time to derive those in the xam hall(still yu must understand the derivations as well). @Jagdish_Singh sir yur golden tips plzz!!
@Churchil_Dwivedi will guide yu better!
