All questions were new but once started solving, they all were solving. There were some tricky questions but reading slowly was the key. My Roll No. Is 109788 & I'm sure to get minimum 75. My first attempt
for network sum... it is tricky with some basic conceptualities.. one is find out avtivity time with EST EFT diff, than look at EFT and based on that construct network. because EFT is nothing but previous event total time of critical path and if u get it.. all sum is easy.
Network problem was purely coceptual. critical path is identified by using total float. when Total float is Zero that activities can form part of critical path
