<human>: Give me a shortened version of the text

Maybe it's just me getting angry because of tough classes, but I feel like different classes should be weighted differently when it comes to GPAs. I'm a genetics major, which means that this semester I'm taking three specialized genetics classes. These classes all require prerequisites to get in, and some of those prerequisites already have their own prerequisites, as well as having no lower than a C+ in certain courses and no lower than a B- in other courses. Yet these classes are curved the same and account for the same when it comes to my GPA.

I then talk to my friends who have all kinds of majors, communications, business, English, sports management, and a surprising amount of interdepartmental studies-(insert broad topic here). I'm not trying to belittle any of these majors, because they can be quite difficult, but students don't necessarily have to keep moving on to more difficult classes, they can plateau, if you will. I don't think any classes should be weighted for less, I just think that certain classes (in all majors, not just the sciences) should be weighted for more, rewarding the students who may have gotten a C in a really difficult class more than a person who got a B in an easy class.
<bot>: Do you think certain classes should be worth more in terms of GPA weight? Or, why isn't this the case?
