Hey there everyone, 23 M here. After multiple Conference outs in CDS and AFCAT SSBs, I'm now looking for financial independence and have chosen CGL as my path towards that objective. Finishing my MSc in Physics this month and ready to dedicate time towards CGL. What are the things I should know, mistakes to avoid and what is the average time required for this exam's prep. I'll be really glad if you people could help..cheers.
