Hey guys currently I have History optional but due to its insurmountable syllabus i have decided to quit it and searching for other I am from Instrumentation Engineering background. Can i give IFoS? It will be immensely helpful to me if you throw some light on Agriculture optional for CSE and IFoS. About its performance, marks, candidates appearing, books required, notes, coaching, test series everything from scratch. Can i prepare it after prelims? If there is any Whatsapp, telegram group let me know.
Thank You
