Just remember:
FCGDAEB
This is the order of Sharps and flats, and also the order of keys.
Going back from C with give you the flat keys. E.g. F has one flat, and that flat is B. Bb (Flattened from earlier) has two flats, B and E.
The sharps are the opposite. G has one sharp, and that sharp is F. D has two sharps, F and C.

Tried to explain it to the best of my ability, not very good at it though.

I use the sentance "Father Christmas Gave Dad An Electric Blanket" to remember this and "Blanket Exploded And Dad Got Cold Feet" to remember the reverse (yes i know, a bit gay :p). Here's a more in depth explanation:

By memorising the major scale formula, T - T - S - T - T - T - S
T = Tone
S = Semitone

I hope this helps

But scales and keys are differnet, right?

all keys are different but to work out a major key or scale you start on the root so start on C and go up by these intervals: T - T - S - T - T - T - S

so the keyof C is C D E F G A B

the key of G is G A B C D E F#
