First, I want to thank all the members of MSE because this community helped me a lot!
But this question is a hard one for me. I want to tell my story with math to all of you in search for an advice.
In high school I liked school math and also some olympiad math as well, but I have never committed too much on it, sincerily I made just the necessary to take good marks . Then, I started university and even if I had fun solving some math puzzles I thought math couldn't be my subject because I considered it abstract in some sense , so I enrolled in a course which is a mix of economics and statistics. But after my pretty introductory course in math for social sciences, I started to see math in another way, not because of the course, but because of the dissatisfaction for it! So I looked around and I found Calculus I by Apostol , and more and more I was reading it more and more I wanted to go on with the reading because I was amazed by the material. So, I started thinking that I like math and I read also some other parts of other books, some I liked some not. But in the end I consider my experience with math pretty satisfactory so I started some elective math courses at my uni to face what studying math really is and to have something to put on my CV maybe to try to enter a graduate school in math after having taken my current degree. I passed the first exam really well even if I didn't like neither the way the material was presented neither how the exam was ; in particular for the preparation of the exam I took a bad habit : looking for patterns in it and nothing else. Also, the material was covered not very in depth but because of this I studied just the necessary without pausing.
Now I'm not so far to take other exams but I can't say I'm satisfied with them because I read the material but nothing the same thing is happening to me, so :
should I consider myself not suited for university math and so quitting my courses and returning to pure self study would be better? Do you think that if this happens at the start of my journey in math uni this will become even worse if I would in the future enroll (if I will be accepted) in a graduate school?
