Help in Preparation confused

I’m learning using the Commounlounge’s Competitive Programming Course

I’m preparing for ZCO and INOI, so is it recommended I use this book by Aulene De or this one, or continue with Commounlounge’s course?

Tagging @mathecodician @kshitij_789, in case any one of them can help.

Others too are free to answer :slight_smile:

Someone please

i would recommend if you can go for Coding Blocks for C++ go for it. Because that way it’ll be easier to have complete and also you’ll have everything completed in few months at-least the basics otherwise searching online and then going for it won’t be as beneficial as needed. the way you are doing is hard way you’ll need to be dependent on somebody in community for doubts.
