PSIR 2027 advice needed !

I am a newbie to pol science. I'm pursuing computer science but also enrolled in IGNOU BA hons pol science course. I don't get time to even open IGNOU books.

To PAPER 1A, 1B, 2A, 2B ki taiyari kaise karu ?? I have full 2 years to put in . SR notes are not enough one of my senior assured me.

Bata dena bhaiyo , beheno aur seniors jinhone clear kar rakha ho ....
