Were the original classes AP based? ( I can't remember)

Is the letter 'Y' a vowel?

Why is the sky blue?

i personally thought energy is more fitting for the new schooling also.

pretty sure the original schooling was energy based. just one big nut off the bat instead of a daily energy investment.

yes, "y" is a vowel.

the sky is not actually blue, it just appears that way because the shorter wavelength light gets absorbed by gas molecules and dispersed through the earth's atmosphere, giving the effect of a blue sky. the longer wavelengths (that would promote a different color sky) happen to move directly through the atmosphere with little absorption by the gas molecules.
