At school I was abysmal at math, my Maths Calculas teacher was less than complimentry.
Maths in Aviation has never posed a problem, I think it is a combination of being genuinely interested in what you are working out and the fact that it it is not just theoretical. It has a definite, tangible quality which when you think it through makes sense.
The subjects you are taking make for interesting conversation in the cockpit, which is also important. You get a little tired of discussing principles of flight sometimes.
Goodluck.
