Hello there,
here are several basic questions you need to make sure before making your final decision.
Strategic questions:
----------------------------
1. what's your purpose to get a graduated degree?
2. what's your sustainable budget (time and fund) for it?
3. are you sure you it will enhance your ultimate goal attainment?
4. If no, why do it?  
    if yes, why are you so sure? (Don't kidding yourself please. )
Tactical issues: 
-----------------------
5. what's your target school?
6. are you confident about yourself?
7. is your family supporting your decision?
Last but not least, it is unwise to sacrifice your potential family possibility for a degree.
Top degree counts, however, the price may be heavy.
Consider it carefully, please.
