About to submit for BOG and then UMPI or TAMC?

[LevelUP]

As far as dedicated time, I would say I can reasonably manage 3-4 hours a day on studies. I have been able to do a fair amount of studying at work between calls, but won't take any tests while on duty because it would be my luck to get a call as soon as I start a timed test!

Here on DF, we consider:
20hr a week - Full-time time student (you can complete a degree in around 6-12 months while working a full-time job)
10hr a week - Part-time student (still enough time for CBE options or light load of scheduled classes)
4hr a week on avg - sporadic student (in  a year, it's possible to complete a similar amount of ACE credits as brick & mortar college students)

It seems like you have more than enough time needed, so you should be good to go.
