I've found that most people enjoy or thrive in one subject but not the other. Type related?
Also, I've found that among math people, there are geometry people and algebra people. People usually like one and dislike the other.
I myself am a math/algebra/calc person. Geometry was far less interesting for me, as well as trigonometry.
My dad(ISTp) has always been good with math/geometry/trig, but he mentioned having problems with calculus.
