acca-jes exemptions

hello, i am new here, so please greet me well

i have a question about exemptions in the jes program
i study Accounting and Finance, and when i graduate i can be exempted from f1 to f4, though if i wanna take the jes program, i wont sit for the f4, but in a variation at my native syllabus, so will i be exempted anyway? or i will have to sit for the f4 variation

Furthermore, is it possible to be exempted after sometime i have already started program?
I mean, i considered starting acca -jes right now from the f5 paper and dont sit the f1-f4 so i will exempted later (when i finish with my bachelor) is that possible?

Finally, does jes bring the same “prestige” and reliability (in accounting/auditing firms) with the “pure” acca, or it is inferior?

Thank you for your time
