think about it from an employers point of view. what relevant experiences/special skills can you bring to the table after 6 years with DSTA? would suggest:

- try for another scholarship with more "transferable"/"exportable" experience.
- go for it without a scholarship if you parents can afford and work for awhile in the us after you graduate.

at the end of the day, what do you want to achieve at the end of the 6years?

your peers whom are as good as you and joined big banks and MNCs in the private sector after graduation would have a much broader outlook/experience and certainly make much more $ if they are top performers.

have fun! : )
