NO! it was said in a comedy movie between the North & the South and the leading star was Red Skelton using the phrase (it"s mighty nice to be back amoung the Magnolias used as a pass word to enter the enemy's territory)
both can be, it depends whether you use 'maths' to mean 'mathematics' (i.e. the subject), or maths class/lesson. you can't be good in mathematics (you should say you are good at mathematics), but you could be good in maths class/ in you maths lesson.
