Learn the Order of Sharps and Flats
The order of Sharps is always F, C, G, D, A, E, and B.
If there is one sharp in the key it would be F. If there were 3 Sharps the Key they would be F, C and G.
The order of Flats is always B, E, A, D, G, C and F.
If there is one Flat in the Key it would be B. If there were 5 Flats in the Key they would be B, E, A, D, and G.
To remember the order of sharps, there is an easy sentence to keep in mind: Fat Cats Go Dancing At Eds Broiler and to remember the order of flats, this sentence will help you: Boogie Ends And Down Go Cats Fast.
To start, use the circle of fifths to find the key you are looking for. Say for example you are looking at the key A Flat, it has four flats. So using the sentence: Boogie Ends And Down Go Cats Fast (B, E, A, D, G, C, F) you can tell the flat B, E, A, and D are the four flats used.
