Link of Parag Gupta Sir's hand-written notes for current ongoing satellite batch https://tinyurl.com/Sat-May-13
I believe these will be really very helpful for students because 2 best and top most faculties for Costing & OR are Parag Gupta sir & Sanjay Aggarwal sir and I am sharing link of their hand written notes. Books of these faculties are available in market.
I will soon upload link of class notes of Sanjay aggarwal sir. They are not available online so need to be scanned.
