Apply to study in China from Pakistan

I'm very worried and trying my best about that:


Now I have a admission letter,VISA application form issued by Beihang University....So.the problem is that Embassador of china in Pakistan is requiring My result of 2nd year(pre-engineering) part-2 which will be declared in the end of august or on 10 september or may be it will be late....I tried my to contact the Board office of pakistan to get my mark sheet argently but they said that it will never declare early....
This time i have my passport,1st year mark sheet,certificate of my matriculation,admision letter, application,Provincial letter or Hope certificate of my 2nd year result issued by my college...etc.

The registration date of university is 15 sep...


I was thinking that Can embassador issue my VISA on the behalf of my provincial letter of 2nd year...Embaasador should be think that university accept me on the behalf of my documents..What your suggestios???
