In need of a serious course of action

Graduating this coming Fall '18 Finance/Accounting Non-target state school 3.5 gpa Currently doing a Spring Boutique IB internship Likely getting a PE internship this summer at a small firm

So with that in mind, I'm here for the same reason everyone else is, to get into the IB job of their dreams. My problem is that I'm graduating at the end of this year and got interested in IB later than I should have. I just got this internship for the Spring which I'm very grateful for, and luckily interviewed with a PE firm for a summer role (TBD if I get it), but am also going to speak with another PE firm. What do I do in terms of next steps? I really can't apply for an SA position for next summer since I'll be graduated, and I don't necessarily want to postpone graduation a whole year to say I'm still in school. On the other hand, I heard it's very hard if not impossible to get a FT at a MM or BB without that SA position. Although I'll probably have a summer role, what do I do in terms of going for FT position or even try an SA for net year?? Just any idea would be great.
