chemistry or physics or maths

I loved chemistry when I was in high school, I never got anything less than a B. Now math on the other hand, that was a different story! I struggled and worked my butt off to get a B in those classes.

For me, the three courses are all difficult. They request good math basement. But in the there courses, I think chemistry is the most difficult one, especially the organic chemistry, I don't like learn chemistry, just because of the organic chemistry existed.
