You can apply for the Student Fare on the Parisian Greater Area Public Transport RATP Imagin R. To apply, you need a proof of enrollment in French, which I will send you via individual emails, and a proof of residence.
Another popular and affordable means of transport in Paris is Velib, a shared bike transport scheme.
If you travel extensively by train in France, you might want to purchase the Carte Avantage Jeune from the national railway system SNCF. It costs €49 and is available for individuals aged 12 to 27 years old. The card can be used until the day before the holder's 28th birthday. It is valid for one year from the start date chosen by the customer at the time of purchase.
Please note that there is no car parking for students on our campus but we have a bike rack.
