Hi, I have enrolled for Shubhra ranjan's PSIR postal correspondent course. The notes sent to me were not legible (two rows on one page). I find the 2017 notes much better to read. Is it sufficient if I cover the static part from 2017 notes and dynamic from the material shared through correspondent. In case the 2017 material is not sufficient which latest notes should I buy from market as there are many available on notesindia, pankajcopiers. I am stuck somewhere and couldn't access the notes sent by Shubhra ranjan institute.
