Is philosophy difficult to learn?

Yes, philosophy emphasizes one's thinking, and the ability of abstract thinking is very important. If you don't think you have this understanding, don't dabble in philosophy easily. You don't have to take him as your major, but you can take philosophy as your hobby. I suggest you find some introductory books on philosophy yourself first, and you will know. I recommend the book General Philosophy written by Professor Jilin University, which is comprehensive and well written. To learn philosophy, to put it mildly, is to learn philosophy well, so don't take philosophy as a major. Of course, you can take more courses in this field during your college years.
