Is it normal that i get d's and f's all of my favorite classes?
I'm in high school, and in the classes I hate, which right now are english and world history, I'm a B student, but when it comes to scientific subjects like math, chemistry, and physics (all of which I'm intensely interested in), It doesn't matter how hard I study. I spend a lot of my free time learning about the things I heard of in class, and I always feel as though I learn the material thoroughly, but obviously I'm doing something wrong. Part of the problem I feel is that I work extremely slowly. It takes me about 90 minutes to complete each assignment, so I end up with no free time, and I still don't get everything done. If I'm taking a test, I can usually only finish about 50-75% of it. It's extremely frustrating because by the end of the year, I always feel like I've learned so much, but I've failed to meet standards which were set beyond my capacity in the first place.
