I scored 45 marks in JEE mains 2014 and 80% in CBSE board Punjab and belong to SC category,what will be my AIR?Will i get any NIT or Thapar?

Dear Suminder, Keeping in mind this year JEE (Main) paper analysis, last year cut offs and only your JEE Main marks (boards not included), some of the institutes you might get are: National Institute of Technology, Rourkela, Spot Round National Institute of Technology, Imphal, Spot Round Indian In

Yes you can have thapa and your job will be secure there
