Participation in law school

Good job! Just a couple of small things -

1. "was one of the best experience" you should say "was one of the best experiences I have had". However, this is quite strong! In England we would be more likely to say a more general "was a fantastic experience".

2. "while I had chance to meet with professional layers from different areas of law" I think you mean "because I had the chance to meet with professional lawyers from different areas of law"

"I feeling excited and need to summarise received experience and knowledge, really shipping and offshore industry despite of permanent crisis and up and downs industry have a huge and brigh future,"

This sentence is less clear. I think you mean:

I am feeling excited and need would like to summarize received my experience and knowledge: really the shipping and offshore industry, despite of permanent crisis, and ups and downs, have has a huge and bright future.

"Thank you ELSA Copenhagen and ESLE Denmark, law firms such as Gorrissen Federspiel, University of Copenhagen, D/S Norden, Gorrissen Federspiel, SKULD, Njord, Hafnia Law Firm, Bech-Bruun, Maersk Line, Søfartsstyrelsen for the warm welcome and the very useful and succinct communication."

This last sentence is basically OK! Well done!
