Dear friend Arpan’
Don’t worry. it’s not a great problem. Friend WBXPRESS has given an information though those are attested copies. If not available a copy of your recommendation letter in that file, no problems too. A copy of your recommendation letter has send to the secretary of your school. You may collect from there. O.K. now relax.
