"fake college to real college" lol... all bible colleges/seminaries are fake buddy - regardless of accreditation.
but in all seriousness, yes you can go from an unaccredited IFB to an accredited college. Most seminaries are case-by-case and they would put you on a probationary level during your first year where you HAVE to maintain a certain GPA. It depends on your college too. Here is a breakdown from what I've seen happen, obviously it isn't accurate - it is simply judging from my friends:
PCC -
accredited now, SBC seminaries (the big 6) will accept. most seminaries will accept including big names such as Talbot, Southern, Trinity. Majority of medical universities will accept Nursing program at PCC which is actually pretty good IMO.
WCBC -
seeking accreditation, all SBC seminaries besides Southern will accept. Dallas, Trinity, Liberty are case-by-case. Talbot will accept if undergrad Bible classes taken. Fuller will not accept.
Hyles Anderson -
no accredit. smaller Baptist seminaries will accept including Maranatha, Baptist Bible, Piedmont, etc. SBC seminaries are case-by-case. Talbot, Fuller, Liberty, will not accept pretty much in all conditions.
Ambassador -
good luck, your screwed. just kidding. Maranatha, Baptist Bible will accept.
all other smaller colleges -
most likely Maranatha will accept. Keep in mind Maranatha is regional which is actually good/better than PCC or WCBC's TRACS.
