Not all schools issue the degree immediately. My nephew finished his BS in engineering at Colorado but didn’t apply for graduation. Instead, he started the master’s degree program and remained an undergrad so eligible for undergrad tuition, loans, state grant ($75 per credit), etc. (he wasn’t Pell eligible because of EFC). The state benefits stopped at 145 credits, but that was enough for him to get the masters.
At any time he could have applied for his BS and dropped the master’s program. This plan is approved (and encouraged) by the school. It is not secret or against the rules.
So check out your state benefits and school policies.
