How to prepare for LRDI from Scratch. I am scoring nil in mocks in this section. Is there any theory for LRDI or only practice?

Watch the videos of particular topic of LIDR and try solving sets on your own, initially you will take lots of time solving the set but as you keep on practicing, time will reduce, Practicing Daily is the key.

Hi, if you're starting from scratch learn the key concepts first. Watch the concept videos of Arrangements, Puzzles, Venn Diagrams, Games & Tournaments first - and practice at least 2-3 sets every day. Take the LRDI daily targets on a regular basis.

Thanks !
