According to my experience as an international student at Institute of Energy Saving and Energy Management (IEE) of Igor Sikorsky Kyiv Polytechnic Institute, there is a lot that I want to talk about but less I can to write; but I want to tell the administration staff and teaching staff of the Institute "Thank you for being with us all that time"  the role & efforts of  IEE family will remain in my memory, proud to be among your Alumni.
