I'm really confused about which one to read - insights secure compilation or insights editorial(Oct 2016 onwards)? Also could someone also throw some light on forum material. Have read only secure before,so I have no clue about forum mains marathon. I also intend to follow vision mains 365. Keeping time limit in mind, what could be the best possible one? I want to keep the sources as less as possible and focus on revision n answer writing. So kindly suggest.
