flymax is right, but i dont think it would restrict anyones ability to fly.
if you consider yourself hopeless, then maybe you should enrol yourself for few mathematics and physics courses at uni, just to help yourself out during training. afterall, you dont need to hold a bachelors or masters in either discipline to be a pilot. Basic understanding should suffice.
i have an uncle who failed his year 12 mathematics. he retook it next year and now is a captain of A310-300.
all comes down to your basic understanding and how wisely you can utilize it during your career as a pilot.
