No Bro,
Dont attach university letters becoz u are applying almost at the end of the file sumbission days,these days are very hectic for them.
If u are applying under SPP....let me tell u again, dont attach extra documents untill they ask for it.
just go with ur academic documents,work experience certificate,offer letter,loan letter and bank statements,ITR.
Ask ur agent.
and my IELTS score was 6.5.
Best of luck.
