If you don't study your favorite major in college or even have no interest at all, I think you can solve this problem by doing the following steps.
First of all, we should correct our mentality. You should keep the right attitude at all times. Even if you don't like your major, you should study your current major well, because even if you change your major, its requirements are basically among the best in this major. Therefore, in order to really get rid of the major in the future courses, we must learn this major well and maintain a correct and good attitude. Otherwise, it is difficult to meet the first basic requirement of changing majors.
Second, pay more attention to the requirements of your school for changing majors, know what you need to do and prepare carefully. You can also learn from seniors who have successfully changed majors. This is one of the best ways to gain other people's experience, which can save you a lot of detours and help you a lot.
Third, if all the above are done, the general school will have a test for students majoring in transfer, and generally some news will be released. You just have to do it according to the above requirements. Of course, if you don't succeed in changing your major, there are still ways. If you are not very exclusive to this major, you can continue to study this major. After all, graduation does not mean that you can graduate with a good major.
While studying your major, you can listen to related courses of your interested major, find information on the Internet, and minor in your favorite major.
If you really turned down your current major, but you didn't succeed in changing your major, you can also choose to repeat it for another year, so that you may know more about what you want, and you may know more about your heart when you fill in your volunteers, and you may get better results.
