hello, I just acquired my spm result and, lets say that i want to apply for foundation in I.T and wish to do it online since K.L is far from my hometown, i got a few questions regarding the online application, hope that i can get some help here.

1. The envelope used to courier my documents must be in 19cmx25cm? Is it compulsory?
2. All the documents I need to send are processing fee, curriculum certificates, IC copy, passport-sized photo, spm result? ( Cert, IC, and result are photocopy and certified)
3. The "educational background" part in the online application form can fit in 11 subjects, but unfortunately I failed my add math, so can i just put the other 10 subjects and leave out my add math?

anyone can help me?
