Major is the main subject that you want to study

u/Pontiac prime provided you with the correct answer. Basically, do you know your field of study? Accounting, architect, engineer, vet, medicine, computer science because if you have a direction then you may consider choosing a University that has a great reputation in that field of study. Often freshmen are still figuring out who they are and what direction they want to take so they choose liberal arts to get a rounded exposure to many fields. University is expensive so unless you are very affluent it may be a good idea to think this over in advance. I’m sure that you know that you have many great choices in France too. Pourquoi ici? Maybe PSU offers a summer exchange program or similar prior to making a commitment? I don’t know, but it’s something to research.
