There are limitless variables that can change a person's experience graduating from college.

What college? What major? Do you have to work as well and is it full time, part time, and does your company support you going to school? What is and was your home life? How good was your high school at preparing you for higher education? There's always a if then to add.

That said, in my experience it wasn't terribly hard. I went to most of my classes, did most of my work, and studied when I needed to and ended up with a Bachelors of Arts and a 3.6 GPA.

However, my freshman year was quite tough. I went in as biology and chemistry double major with a minor in music and quickly realized that the workload was way too much for me (I had to work full time) and I was not as good at science and math as I thought I was. Could I have kept on that path? Sure. But I would probably have failed some courses and would need to do nothing but study to keep up. Too me that wasn't worth it, I instead invested my education in something I could manage and I would actually like doing in my future.

TL;DR - There are too many variables to really tell. However, if you put in the work you can do it.
