Ever since I switched my major, I realized something that isn't exactly fair: not all majors are hard.
The one I had just switched from was a bear: I had to get help with every assignment, did okay on the tests, and found myself zoning out sometimes because I wasn't comprehending the material. With this major, I ace every assignment and test and I completely understand what's going on (partly because I knew what some of the textbooks were talking about already, as they seemed to be common sense). What gives?
Easiness of a major can really depend on how your brain works. Some people are more science minded than me, so they probably think that biology is the easiest thing on the face of the earth, where I think English is a piece of cake.
Besides this fact, the curriculum is different for nearly every major. Now some of you are probably thinking "well, duh," but hear me out: if you pick a major, you need to be willing to take the baggage (or lack thereof) that goes with it.
Science-based classes and engineering classes will almost always have a lab attached to the course, which is more time you need to take to get a good grade. English classes require more essays than some other classes, and music majors will have to most likely take a lot of personal time to rehearse a piece they need to play for their final. Sure, someone may "ooo" and "ahh" about being a teacher, but they didn't expect having a block schedule or student teaching.
For other majors, it seems like there isn't much work that we have to do at all. We have our reading discussions, weekly chats, and maybe a project sprinkled here and there, but it isn't nearly as intensive as some others.
Some students may be okay with this, and some may think that they aren't getting the most out of their major. So the bottom line is: know what you are getting into when you pick a major.
Do research into the majors offered at your school and ask your adviser about the work loads before you decide to commit. If I had done that my freshman year, it would have saved me a lot of grief hoping that my credits would carry over from another major because I didn't like it enough to deal with the work load.
Ask other classmates what they think of their majors, and think long and hard about what your limits are when it comes to schoolwork. With some, the work is absolutely worth it to you. Some are absolutely not.
