do you mean you want to study an information systems sub major?
It may be wise to ask your course coordinater who can than refer you to an appropriate source. If you check the B Bus&Com degree there is a Info Systems Practice sub major. On the SoM website [i dont think you have access to it] there is an E-business Information systms sub major available too.
