i went to fte about 9 months ago 2 do the assesment test, in the same position as u with math not being my strong point, i didn't get a place in the end due to the math exam! i was told i would have great difficulty with the atpl's with subjects like gen nav & flight planning, anyway i didn't let fte's results get me down and decided to go the modular route, i just passed all 14 subjets with a 94% average, as far as the maths and physics go if u work hard while on the atpl's you'll pick it up very fast, just remember if it doesn't go your way with fte there are lots of other flight schools around
best of luck.
