School codes

Hi.
I cannot find enough codes or they do not work.

Math 1 = 4
Math 2 = 5
Art 8 = 4
English 6 = 0
Comp 4 = 3
Comp 7 = 4

6 Codes for 2 Doors with 4 Codes?
English 6 cannot be 0 because i cannot use 0 in the codes because it deletes always other codes.

Somethign is going very wrong here.
