From the title, I thought that it was something negative, but it was a good thing, right? I have some friends in Sorbonne, and from what I heard, that university is great, and it provides a lot of resources for students, and even for students from other universities. My university also provides access to different resources, documents, research and so on, but I still use a lot of extra things, especially when I need to write something. Here is one resource https://edubirdie.com/examples/problem-solution-essays/ which helped me earlier this week to write my paper. It was maybe the second time I used something like this, but it was beneficial. So even if the university provides different sources, it's still a good idea to look for something else.
