I have completed Shubhra ranjan tablet course of 2024. But due to State Pcs mains, I lost in touch with PSIR for over a year.
I am starting to prepare for next year’s attempt. All the PSIR serious students, is there any course (Sleepyclasses, Piyush Chaubey, Synopsis UPSC), or any resource material that can be used as value addition apart from my notes.
I needed a structured revision plan along with test series, that’s why I was looking for a course that could help me in this. But was confused which to take. Can anyone suggest me please?
Also, if anyone has solved PYQ of PSIR, can you share ?
