Do you like it or not? Specialized elective courses are only a few hours, and nothing can be learned at all. If you choose mixed credits, you should have an undergraduate guide to see what types the college requires, such as how many points the humanities, social sciences and arts require. It doesn't matter whether you like it or not. Credit is very important. If you choose unreasonable advanced courses, you will be worried to death. There is no need to make elective courses so tight. You don't think there will be no classes for the next three years. There are not many classes that need attention, as long as the credits are reasonable. Teachers in public elections will choose to ask seniors for the first time, and then they will choose to ask classmates. As long as it's not a perverted teacher, everything else is the same. To sum up, professional elective courses are similar to public elective courses, and you can't learn anything by mixed credits. .....
