Extension of my tier 4 visa

[Virajraj]

Dear there

I am currently doing acca with bcu, applied for 4 module but in two session of exam could not be able to clear any paper it's just because of I find it bit difficult. My visa expire in Aug and I just formally speaks to my uni why I am failed but they said they can't issue me a cas now so what can I do ? Is there any uni like bpp who can give me chance to resit again in those module.
