Fear of admission being revoked

Hey everyone. I have been accepted into a university and already paid my enrollment fee. Thing is, I still gotta submit my WES evaluation of IGCSE. I graduated from a British curriculum based school so I graduated at year 11. I have read on different sites with some saying that IGCSEs are equivalent to US High school diplomas and some saying they are only equivalent to grade 10. Dont know what WES will evaluate it into. But anyways, can the uni revoke my admittance if WES evaluates the IGCSE into US grade 10? Obviously I never lied about anything on my application so does the WES evaluation count towards my fate? Please help me out. I dont know when the deadline is and an I-20 wont be issued until I finish the WES procedure, which will take about a month. Oh yea and I have contacted the Uni if that is what u wanna suggest. They said although A levels are required, an O level is just fine. However, the catch is they never clearly clarified about needing to finish year 12 or so.

Help me pls stressing out here :frowning:
