Will the US NAVY accept this HS DIPLOMA?

Online high schools are frowned upon because they're so easy to cheat on. If they don't make you do any proctored exams there's no way they can confirm you're actually the one doing the work. Because of that, nine times out of ten the military will look at a online diploma as a Tier 3, or even lower than a GED, which is a Tier 2. In other words, you might as well throw that $219 in the trash. If you want to wait until Tuesday I could look up the school on my government computer to see what Tier level it actually falls under. Or, you can just call your Navy recruiter on Monday and see what they say. As for the University of Phoenix; it's an accredited college and some of their exams are proctored. That's why the Navy can accept them. It's up to you what you want to do from here, either join the Army now or get your 15 semester hours and join the Navy later. The 100 level part is true for the most part, the recruiter probably said "just get the credits" because most classes will be 100 level by default. If you take a remedial class that won't be 100 level and it won't count.
