confused

i have 3 choices deciding where i should go, but still, i'm so confused and not decided yet.

1) To be graduated in CIS degree, and then pursuing higher education in Ms in Computer Science.

2) or just straight away to get double majors in CIS degree and BS of Applied Mathematics.

3) Should i take the easily way to success to be graduated in CIS degree?. 

The truth is that if after i graduated, i won't go back to school for my another study life. In other words, I'm enough for study and going to put more efforts on real world experiences such as work in a teams, decision making, etc.

argsss...  the decisions really screw me up...
