I am not sure about this. But I heard that top-ranked universities have a significant role in getting tier 4 visa. In that case, you are on the safe side because derby got a gold status in TEF. Above all of that home office is the primary decision maker, so we cant be certain about visa decision :( ...

Same situation bro...I opted for priority service but its been 15 working days..still no email or text from UKVI . Which uni are you applying?

still no update Did they reply you?

MBA with placement. what about you?

University Of Northampton. My previous Visa application was refused by Canada and Poland. Though I got a fully funded scholarship from Poland but still got refused. That's why I am bit worried, it might affect my tier 4 visa application and I might not get the visa decision within 5 working days.

Please let us know your visa outcome. I also submitted my application on 9th may using priority service. Btw in which Uni are you going?
