Advices for incoming PE intern

Hey guys, 

This Summer I'm intering for 6 weeks at a big American PE fund in their London office. About myself: I'm a first year student of International Economics and Management at Bocconi University, know microsoft office well and have the basics of python, speak 4 languages and I plan on working in IB after uni. Could you give any advices on how to approach this incredible opportunity and maybe also things I should now before the internship begins? 

Thanks
