Attractions Paris

[mel]

Hi guys,
I'm a student and right now I'm living in Paris to do an internship and make new experiences. Unfortunately most of the attractions are really expensive and as a student it's not easy to afford them. That's why I want to ask you if you have any insider-tips or know some possibilities to save money. I only know a website where you can get 20 % on attractions and restaurants.
I look forward to hearing from you soon!
