I have gone through the recommended sources like: NCERTs,Laxmikanth,Spectrum,GCL,Singhania,Ramesh,Shamkar for static parts and Vision,Insights and Unacademy for Dynamic parts. My score in prelims is 104~106,so I missed mains by a narrow margin. I am a working professional and I give 4-5 hrs for preparation daily. What further should be done to ensure 120+ score in 2018 so that I can land in Mains 2018? I scored 100+ thrice in Vision test series and thrice in Insights test series. I committed mistakes in the questions like: TRAFFIC,Kakatiya Port,National park in south India,Pulicat lake,Vidyanjali, Moving of Lions,NCS,AMOLED etc.I have done multiple revisions of booklets of Vision and Insights before the exam. Please guide me in this regard.
