around 66.66 marks CE 2nd session OBC category. Chance of any PSU ? NLC NOT FILLED

Yes, chances are there with this score so better to apply for more number of PSUs as per the eligibility given by them and NLC was done with application process on 31st Jan 2017 so there you cannot apply now. But there are many other PSUs still left with the application forms like BSNL, NPCIL, PowerGrid, Cabinet Secretariat, Govt. of India and etc where you can apply. And to make it more clear, I am providing you the link which you can go through to check where, when and how you can apply in PSU -
