Fastest way to get into graduate school

[megaworp]

Thank you for your answers! Filling all the information to give you a clearer picture:

Your Location: Athens, Greece
Your Age: 30
What kind of degree do you want?: BA in psychology or easiest Bachelor's degree to be able to enroll in Psychology MS in an American College in Greece.
Current Regional Accredited Credits: NA

School Name Total Credits: NA

Current ACE, CLEP, or NCCRS Credits: NA

Provider Total Credits: NA

Any certifications or military experience? No

Budget: Not an issue. I'd like to go the cheapest route possible, but will consider spending more for easy and fast.  
Commitments: I have my own company and have a LOT of time to spare for studying and fast tracking. I just want to enroll in the MS asap, either by conversion from a different Bachelor's or straight from Psych degree.
Dedicated time to study: I can study as much as is needed during the night or weekends as long as my schedule is free. 3-4 hours a day is doable.
Timeline: Finishing the courses required for the degree as fast as possible would be ideal.  I would like to finish within a year or 1.5 years.
Tuition assistance/reimbursement: No clue but would love if any unis (UMPI for example) could assist me as an international student.

I don't really know about testing-out vs competency based, what I know is psychology has always been a favorite subject of mine on which I've read a lot so I have the assumption that I would just breeze through the undergrad course, then again I might be totally wrong.. Or perhaps going for a different BA is simpler and faster, but that's what I'm here to find out!

To reiterate, my end goal is to be accepted into ACG's Psychology MS, for which I need a bachelor's. However, if I have a psych degree I won't have to go through the 2-4 term conversion course to enroll in the MS.

Is UMPI's Psychology YourPace doable within a year? I don't think I have any credits to transfer from my old school (electrical engineering school in Greece) and I have nothing in regards of Sophia, etc. Otherwise is any other BA doable, and what would the cost be? Thank you soooo much!
