Asset Management fair in my city next week. Any suggestion before i go?

Who am I: 21, live in Europe, Undergraduate, studying Finance in a non target school and i will get bachelor's degree in September, had 2 years of working experience in sales (back and front office - not related to finance) while studying at school that caused low Gpa, but i'm currently improving it.

Body: I am currently looking for an internship in AM. Already sent applications to bigger firms with December deadline but had no answer. Here in Southern Europe however many firms and banks accept applications even in May for the summer internship, so i am contacting a lot of firms in these days.

Now, i found out that next week there will be a big fair of Asset Management in my city. There will be a lot of firms, from small consulting firms to the top players of AM. Students can enter, so i definitely want to go in order to network and hopefully to find someone who may help me in my internship search.

Do you have any suggestion for me? There is something I should absolutely say/do, and something I should absolutely avoid there? Anything i should prepare apart of my Cv? Looking at my history, are there any real chances to get an internship in AM?
